feat: Added methods for creating and deleting composite indexes (#248)

This PR fixes an issue with the `owlbot.py` file which prevented [google/cloud/datastore_v1](https://github.com/googleapis/python-datastore/commits/main/google/cloud/datastore_v1) from being updated. This PR also brings the client up to date with the generated client in googleapis-gen [here](https://github.com/googleapis/googleapis-gen/tree/master/google/datastore).

chore: update owlbot.py to properly copy folders from googleapis-gen
fix(deps): require google-api-core >= 1.28.0
docs: list oneofs in docstring
feat: add context manager support in client
fix: add 'dict' annotation type to 'request'
fix: add async client to %name_%version/init.py
feat: support self-signed JWT flow for service accounts 
feat: Added methods for creating and deleting composite indexes
