fix(pubsub): retry GOAWAY errors (#4313)
The frontend server for Pub/Sub might occasionally emit GOAWAY errors which are currently not retried. This is not unique to the Go client, though the categorization as `UNKNOWN` vs `UNVAILABLE` is a golang-GRPC issue. Although UNKNOWN [should not generally be retried](, this will unblock users of `Receive` until the grpc library can be changed. See internal cl/377393940 for a similar fix in another Go library.

Fixes #4257.
