Adding kwargs to gazelle_python_manifest (#1289)

Adding kwargs to gazelle_python_manifest, so we can set the tags and
size to the test. This is similar to:


https://github.com/bazelbuild/rules_python/blob/5b8fa22a2f22501b18b4aea97c5dbfe3a6913a0c/python/pip_install/requirements.bzl#L20-L62

Alternatively, we can add individual `go_test` attributes as needed.
Please advice which way is preferred.
