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
- [x] Allow variable overrides (with shortcut) in targets
- [x] Don't allow to provide complex variables via flag or env variable
- [x] Fail validation if complex value is used but not `type: complex`
provided
- [x] Support using variables inside complex variables 

## Tests
Added unit tests

Resolve variable references inside variable lookup fields (#1368)
## Changes
Allows for the syntax below

```
variables:
  service_principal_app_id:
    description: 'The app id of the service principal for running workflows as.'
    lookup:
      service_principal: "sp-${bundle.environment}"
```

Fixes #1259

## Tests
Added regression 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).

Allow use of variables references in primitive non-string fields (#1219)
## Changes

This change enables the use of bundle variables for boolean, integer,
and floating point fields.

## Tests

* Unit tests.
* I ran a manual test to confirm parameterizing the number of workers in
a cluster definition works.

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
