Fix variable overrides in targets for non-string variables (#1397)
Before variable overrides that were not string in a target would not
work. This PR fixes that. Tested manually and via a unit test.

Return `diag.Diagnostics` from mutators (#1305)
## Changes

This diagnostics type allows us to capture multiple warnings as well as
errors in the return value. This is a preparation for returning
additional warnings from mutators in case we detect non-fatal problems.

* All return statements that previously returned an error now return
`diag.FromErr`
* All return statements that previously returned `fmt.Errorf` now return
`diag.Errorf`
* All `err != nil` checks now use `diags.HasError()` or `diags.Error()`

## Tests

* Existing tests pass.
* I confirmed no call site under `./bundle` or `./cmd/bundle` uses
`errors.Is` on the return value from mutators. This is relevant because
we cannot wrap errors with `%w` when calling `diag.Errorf` (like
`fmt.Errorf`; context in https://github.com/golang/go/issues/47641).

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

Allow referencing bundle resources by name (#872)
## Changes
Now we can define variables with values which reference different
Databricks resources by name.
When references like this, DABs automatically looks up the resource by
this name and replaces the reference with ID of the resource referenced.
Thus when the variable is used in the configuration it will contain the
correct resolved ID of resource.

The resolvers are code generated and thus DABs support referencing all
resources which has `GetByName`-like methods in Go SDK.

### Example

```
variables:
  my_cluster_id:
    description: An existing cluster.
    lookup: 
      cluster: "12.2 shared"

resources:
  jobs:
    my_job:
      name: "My Job"
      tasks:
        - task_key: TestTask
          existing_cluster_id: ${var.my_cluster_id}

targets:
  dev:
    variables:
      my_cluster_id:
        lookup: 
           cluster: "dev-cluster"
```

## Tests
Added unit test + manual testing

Initialize variable definitions that are defined without properties (#966)
## Changes

We can debate whether or not variable definitions without properties are
valid, but in no case should this panic the CLI.

Fixes #934.

## Tests

Unit.

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

Added support for bundle.Seq, simplified Mutator.Apply interface (#403)
## Changes
Added support for `bundle.Seq`, simplified `Mutator.Apply` interface by
removing list of mutators from return values/

## Tests
1. Ran `cli bundle deploy` and interrupted it with Cmd + C mid execution
so lock is not released
2. Ran `cli bundle deploy` top make sure that CLI is not trying to
release lock when it fail to acquire it

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.

2. process environment variable
3. in the bundle config itself

## Tests
