Don't fail while parsing outdated terraform state (#1404)
`terraform show -json` (`terraform.Show()`) fails if the state file
contains resources with fields that non longer conform to the provider
schemas.

This can happen when you deploy a bundle with one version of the CLI,
then updated the CLI to a version that uses different databricks
terraform provider, and try to run `bundle run` or `bundle summary`.
Those commands don't recreate local terraform state (only `terraform
apply` or `plan` do) and terraform itself fails while parsing it.
[Terraform
docs](https://developer.hashicorp.com/terraform/language/state#format)
point out that it's best to use `terraform show` after successful
`apply` or `plan`.

Here we parse the state ourselves. The state file format is internal to
terraform, but it's more stable than our resource schemas. We only parse
a subset of fields from the state, and only update ID and ModifiedStatus
of bundle resources in the `terraform.Load` mutator.

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).

Fix metadata computation for empty bundle (#939)
## Changes
This PR fixes metadata computation for empty bundle. Before we would
error because the `terraform.Load()` mutator errors on a empty / no
state file.

## Tests
Failing integration tests now pass.

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.

Improved error message when 'bricks bundle run' is executed before 'bricks bundle deploy' (#378)
## Changes
Improved error message when 'bricks bundle run' is executed before
'bricks bundle deploy'

The error happens when we attempt to load terraform state when it does
not exist.

The best way to check if terraform state actually exists is to call
`terraform show -json` and that's what already happens here

https://github.com/databricks/bricks/compare/main...error-before-deploy#diff-8c50f8c04e568397bc865b7e02d1f4ec5b18379d8d32daddfeb041035d804f5fL28

Absence of `state.Values` indicates that there is no state and likely
bundle was just never deployed.

## Tests
Ran `bricks bundle run test_job` on a new non-deployed bundle.

**Output:**

`Error: terraform show: No state. Did you forget to run 'bricks bundle
deploy'?`

Running `bricks bundle deploy && bricks bundle run test_job` succeeds.

Add mutators to pull and push Terraform state (#288)
## Changes

Pull state before deploying and push state after deploying.

Note: the run command was missing mutators to initialize Terraform. This
is necessary if the cache directory is removed between running "deploy"
and "run" (which is valid now that we synchronize state).

## Tests

Manually.
