## 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.
## 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

```
## 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.
## 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.

## 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.
