Support for GRPC interractions

[Dimitrios Dedoussis]

This issue is about adding a stub that wraps the https://pypi.org/project/grpcio/ package to support cassettes for GRPC interactions.

Submitting this issue to see whether a contribution for supporting such a feature would be welcome. If yes, I'm happy to raise a PR.

Also having the same issue.

We are trying to test Google Cloud Vision interactions, which uses gPRC under the hood.

[Max Countryman]

I'm also interested in this for testing Google Ads interactions, which also utilize gRPC.

Is this something that would be pulled into vcrpy?

[David Humbla]

Count me in for alpha testing :)

[Abdullah Selek]

Interested in gRPC support too 👍

Hello!
Have you guys any news about the grpc recording implementation?

[John Vandivier]

@dedoussis there seems to be a good amount of support, are you able to go ahead and make a PR to nudge the convo along?

cc @kevin1024 in case I missed convo on this elsewhere or we are waiting on a maintainer decision before pr

I really need grpc support for accessing Google texttospeech and speechtotext API.
