BREAKING CHANGE:
With this change we remove the following deprecated APIs
- `TslintFixTask`
- `TslintFixTaskOptions`
**Note:** this only effects schematics developers.
The dev-infra tooling now directly provides public API change testing capabilities that leverage the `api-extractor` utility. These new testing capabilities are shared with framework and components.
`ts-api-guardian` has been removed as a dependency as a result.
