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

Added support for top-level permissions (#928)
## Changes
Now it's possible to define top level `permissions` section in bundle
configuration and permissions defined there will be applied to all
resources defined in the bundle.

Supported top-level permission levels: CAN_MANAGE, CAN_VIEW, CAN_RUN.

Permissions are applied to: Jobs, DLT Pipelines, ML Models, ML
Experiments and Model Service Endpoints

```
bundle:
  name: permissions

workspace:
  host: ***

permissions:
  - level: CAN_VIEW
    group_name: test-group
  - level: CAN_MANAGE
    user_name: user@company.com
  - level: CAN_RUN
    service_principal_name: 123456-abcdef
```

## Tests
Added corresponding unit tests + ran `bundle validate` and `bundle
deploy` manually

Make resource and artifact paths in bundle config relative to config folder (#708)
# Warning: breaking change

## Changes
Instead of having paths in bundle config files be relative to bundle
root even if the config file is nested, this PR makes such paths
relative to the folder where the config is located.

When bundle is initialised, these paths will be transformed to relative
paths based on bundle root. For example,
we have file structure like this
```
- mybundle
| - bundle.yml
| - subfolder
| -- resource.yml
| -- my.whl
```

Previously, we had to reference `my.whl` in resource.yml like this,
which was confusing because resource.yml is in the same subfolder
```
sync:
  include:
    - ./subfolder/*.whl
...
tasks:
  - task_key: name
    libraries:
      - whl: ./subfolder/my.whl
...
```

After the change we can reference it like this (which is in line with
the current behaviour for notebooks)

```
sync:
  include:
    - ./*.whl
...
tasks:
  - task_key: name
    libraries:
      - whl: ./my.whl
...
```

## Tests
Existing `translate_path_tests` successfully passed after refactoring.

Added a couple of uses cases for `Libraries` paths.

Added a bundle config tests with include config and sync section

Added run_as section for bundle configuration (#692)
## Changes
Added run_as section for bundle configuration.

This section allows to define an user name or service principal which
will be applied as an execution identity for jobs and DLT pipelines. In
the case of DLT, identity defined in `run_as` will be assigned
`IS_OWNER` permission on this pipeline.

## Tests
Added unit tests for configuration.

Also ran deploy for the following bundle configuration

```
bundle:
  name: "run_as"

run_as:
  # service_principal_name: "f7263fcc-56d0-4981-8baf-c2a45296690b"
  user_name: "lennart.kats@databricks.com"

resources:
  pipelines:
    andrew_pipeline:
      name: "Andrew Nester pipeline"
      libraries:
        - notebook:
            path: ./test.py

  jobs:
    job_one:
      name: Job One
      tasks:
        - task_key: "task"
          new_cluster:
            num_workers: 1
            spark_version: 13.2.x-snapshot-scala2.12
            node_type_id: i3.xlarge
            runtime_engine: PHOTON
          notebook_task: 
            notebook_path: "./test.py"
```

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
