Mypy-boto3

Added

- `[builder]` `S3Outposts` service support
- `[builder]` `TimestreamQuery` service support
- `[builder]` `TimestreamWrite` service support
- `[all]` `ResponseMetadata` shape to all `...Output` type defs
- `[all]` Python 3.9.0 support

Fixed

- `[all]` Incorrectly sorted imports in `client.pyi`
- `[all]` Pylint errors in generated modules

Added

- `SSOAdmin` service support
- `RedshiftDataAPIService` service support

Fixed

- Unsupported services no longer added to `all` extra requirements
- Improved imports sorting in generated files

Fixed typo in deployment script

Fixed

- `client.exceptions` type annotations are included to each service and do not require `botocore` installed
- Failing `<package>.client` import if `boto3-stubs` package is not installed

Notes

Unfortunately, I completely overlooked that `pyi` files are not importable, so direct imports were broken during adding `pyright` support. The solution is hacky, but it is working - all service packages contain `py` files identical to `pyi`. `*.py` files are auto-formatted with `pyi` rules to keep line numbers the same.

Fixed

- Import error from stub libraries
- `pylint` not being happy with generated files
