Alias variables block in the `Target` struct (#1748)
## Changes
This PR aliases and overrides the schema associated with the variables
block in `target` to allow for directly specifying a variable value in
the JSON schema (without an levels of nesting). This is needed because
this direct value is resolved by dynamically parsing the configuration
tree.

## Tests
Existing unit tests.

Use dynamic walking to validate unique resource keys (#1614)
## Changes
This PR:
1. Uses dynamic walking (via the `dyn.MapByPattern` func) to validate no
two resources have the same resource key. The allows us to remove this
validation at merge time.
2. Modifies `dyn.Mapping` to always return a sorted slice of pairs. This
makes traversal functions like `dyn.Walk` or `dyn.MapByPattern`
deterministic.

## Tests
Unit tests. Also manually.

Override complex variables with target overrides instead of merging (#1567)
## Changes
At the moment we merge values of complex variables while more expected
behaviour is overriding the value with the target one.

## Tests
Added unit test

Added support for complex variables (#1467)
## Changes
Added support for complex variables

Now it's possible to add and use complex variables as shown below

```
bundle:
  name: complex-variables

resources:
  jobs:
    my_job:
      job_clusters:
        - job_cluster_key: key
          new_cluster: ${var.cluster}
      tasks:
      - task_key: test
        job_cluster_key: key

variables:
  cluster:
    description: "A cluster definition"
    type: complex
    default:
      spark_version: "13.2.x-scala2.11"
      node_type_id: "Standard_DS3_v2"
      num_workers: 2
      spark_conf:
        spark.speculation: true
        spark.databricks.delta.retentionDurationCheck.enabled: false
```

Fixes #1298

- [x] Support for complex variables

Return diagnostics from `config.Load` (#1324)
## Changes

We no longer need to store load diagnostics on the `config.Root` type
itself and instead can return them from the `config.Load` call directly.
It is up to the caller of this function to append them to previous
diagnostics, if any.

Background: previous commits moved configuration loading of the entry
point into a mutator, so now all diagnostics naturally flow from
applying mutators.

This PR depends on #1319.

## Tests

Unit and manual validation of the debug statements in the validate
command.

Use dynamic configuration model in bundles (#1098)
## Changes

This is a fundamental change to how we load and process bundle
configuration. We now depend on the configuration being represented as a
`dyn.Value`. This representation is functionally equivalent to Go's
`any` (it is variadic) and allows us to capture metadata associated with
a value, such as where it was defined (e.g. file, line, and column). It
also allows us to represent Go's zero values properly (e.g. empty
string, integer equal to 0, or boolean false).

Using this representation allows us to let the configuration model
deviate from the typed structure we have been relying on so far
(`config.Root`). We need to deviate from these types when using
variables for fields that are not a string themselves. For example,
using `${var.num_workers}` for an integer `workers` field was impossible
until now (though not implemented in this change).

The loader for a `dyn.Value` includes functionality to capture any and
all type mismatches between the user-defined configuration and the
expected types. These mismatches can be surfaced as validation errors in
future PRs.

Given that many mutators expect the typed struct to be the source of
truth, this change converts between the dynamic representation and the
typed representation on mutator entry and exit. Existing mutators can
continue to modify the typed representation and these modifications are
reflected in the dynamic representation (see `MarkMutatorEntry` and
`MarkMutatorExit` in `bundle/config/root.go`).

Required changes included in this change:
* The existing interpolation package is removed in favor of
`libs/dyn/dynvar`.
* Functionality to merge job clusters, job tasks, and pipeline clusters
are now all broken out into their own mutators.

To be implemented later:
* Allow variable references for non-string types.
* Surface diagnostics about the configuration provided by the user in
the validation output.
* Some mutators use a resource's configuration file path to resolve
related relative paths. These depend on `bundle/config/paths.Path` being
set and populated through `ConfigureConfigFilePath`. Instead, they
should interact with the dynamically typed configuration directly. Doing
this also unlocks being able to differentiate different base paths used
within a job (e.g. a task override with a relative path defined in a
directory other than the base job).

## Tests

* Existing unit tests pass (some have been modified to accommodate)
* Integration tests pass

Consolidate bundle configuration loader function (#918)
## Changes

There were two functions related to loading a bundle configuration file;
one as a package function and one as a member function on the
configuration type. Loading the same configuration object twice doesn't
make sense and therefore we can consolidate to only using the package
function.

The package function would scan for known file names if the specified
path was a directory. This functionality was not in use because the
top-level bundle loader figures out the filename itself as of #580.

## Tests

Pass.

Move bundle configuration filename code (#917)
## Changes

This is unrelated to the config root so belongs in a separate file (this
was added in #580).

Renamed `environments` to `targets` in bundle configuration (#670)
## Changes
Renamed Environments to Targets in bundle.yml.

The change is backward-compatible and customers can continue to use
`environments` in the time being.

## Tests
Added tests which checks that both `environments` and `targets` sections
in bundle.yml works correctly

First look for databricks.yml before falling back to bundle.yml (#580)
## Changes
* Add support for using `databricks.yml` as config file. If
`databricks.yml` is not found then falling back to `bundle.yml` for
backwards compatibility.
* Add support for `.yaml` extension.
* Give an error when more than one config file is found

## Tests
* added unit test
* manual testing the different cases

Add development runs (#522)
This implements the "development run" functionality that we desire for DABs in the workspace / IDE.

## bundle.yml changes

In bundle.yml, there should be a "dev" environment that is marked as
`mode: debug`:
```
environments:
  dev:
    default: true
    mode: development # future accepted values might include pull_request, production
```

Setting `mode` to `development` indicates that this environment is used
just for running things for development. This results in several changes
to deployed assets:
* All assets will get '[dev]' in their name and will get a 'dev' tag
* All assets will be hidden from the list of assets (future work; e.g.
for jobs we would have a special job_type that hides it from the list)
* All deployed assets will be ephemeral (future work, we need some form
of garbage collection)
* Pipelines will be marked as 'development: true'
* Jobs can run on development compute through the `--compute` parameter
in the CLI
* Jobs get their schedule / triggers paused
* Jobs get concurrent runs (it's really annoying if your runs get
skipped because the last run was still in progress)

Other accepted values for `mode` are `default` (which does nothing) and
`pull-request` (which is reserved for future use).

## CLI changes

To run a single job called "shark_sighting" on existing compute, use the
following commands:
```
$ databricks bundle deploy --compute 0617-201942-9yd9g8ix
$ databricks bundle run shark_sighting
```

which would deploy and run a job called "[dev] shark_sightings" on the
compute provided. Note that `--compute` is not accepted in production
environments, so we show an error if `mode: development` is not used.

The `run --deploy` command offers a convenient shorthand for the common
combination of deploying & running:
```
$ export DATABRICKS_COMPUTE=0617-201942-9yd9g8ix
$ bundle run --deploy shark_sightings
```
The `--deploy` addition isn't really essential and I welcome feedback 🤔
I played with the idea of a "debug" or "dev" command but that seemed to
only make the option space even broader for users. The above could work
well with an IDE or workspace that automatically sets the target
compute.

One more thing I added is`run --no-wait` can now be used to run
something without waiting for it to be completed (useful for IDE-like
environments that can display progress themselves).
```
$ bundle run --deploy shark_sightings --no-wait
```

Rename bricks -> databricks (#389)
## Changes

Rename all instances of "bricks" to "databricks".

## Tests

* Confirmed the goreleaser build works, uses the correct new binary
name, and produces the right archives.
* Help output is confirmed to be correct.
* Output of `git grep -w bricks` is minimal with a couple changes
remaining for after the repository rename.

Store relative path to configuration file for every resource (#322)
## Changes

If a configuration file is located in a subdirectory of the bundle root,
files referenced from that configuration file should be relative to its
configuration file's directory instead of the bundle root.

## Tests

* New tests in `bundle/config/mutator/translate_paths_test.go`.
* Existing tests under `bundle/tests` pass and are augmented to assert
on paths.

Move mutator interface to top level bundle package (#105)
While working on artifact upload and workspace interrogation I realized
this mutator interface needs to:
1. Operate at the whole bundle level so it can apply to both
configuration and internal state
2. Include a `context.Context` parameter for a) long running operations
and b) progress reporting

Previous interface:
```
Apply(*config.Root) ([]Mutator, error)
```

New interface:
```
Apply(context.Context, *Bundle) ([]Mutator, error)
```

Skeleton for configuration loading and mutation (#92)
Load a tree of configuration files anchored at `bundle.yml` into the
`config.Root` struct.

All mutations (from setting defaults to merging files) are observable
through the `mutator.Mutator` interface.
