Taskcluster-taskgraph

Added

- A `taskgraph init` command to bootstrap projects on Firefox-CI

Fixed

- DONTBUILD in a commit message now works for Github pushes

Changed

- `fetch-content` script now uses `unzip -q` to avoid polluting logs

Added

- Python 3.11 is now tested in CI
- Support for `.tgz` file extension in `fetch-content` script
- Extra arguments now forwarded from `job.toolchain` transforms to `job.run_task`
- All calls to `util.yaml.load_yaml` are now memoized
- Support for `command-context.from-file` in `run_task` transforms
- Worker provisioner / type can be formatted with alias and trust-domain in `config.yml`

Fixed

- `util.vcs.get_commit_message` actually uses its `revision` parameter

Fixed

- `util.hash.hash_paths()` takes much less time to run when provided with 10+ patterns.

Added

- `shipping-phase` attribute in `task` and `job` transforms.
