Common Libraries

We have introduced versioned clients for many services. The version is that of
the GCP service. While this naming convention is more verbose, it allows us to
support clients for multiple versions of a GCP service from within the same
library (e.g. speech_v1::SpeechClient and speech_v2::SpeechClient). See
#10170 for more details.

• fix: retries for GetIamPolicy, TestIamPermissions (#10957)
• doc: improve description for "terminate" group (#10950)
• fix(common): fewer spurious warnings in the log (#10811)
