Code Review
This pull request introduces a custom retry predicate, _rst_stream_aware_predicate, for ReadRows operations in both the asynchronous and synchronous Bigtable clients. This predicate treats specific InternalServerError messages (such as "rst_stream") as ServiceUnavailable errors to allow them to be retried. The review feedback points out a potential AttributeError in the predicate's implementation if e.message is None, and suggests adding a type check to ensure e.message is a string before calling .lower().

According to go/rst_stream, `INTERNAL` errors with error messages related to an `rst_stream` error should be interpreted as `UNAVAILABLE` errors instead of internal errors. This PR creates a custom retry predicate to allow retrying of `INTERNAL` errors with rst_stream specific error messages if the `ServiceUnavailable` exception is allowed to be retried. --------- Co-authored-by: Daniel Sanche <sanche@google.com>

is this right? why would it be both ServiceUnavailable and InternalServerError?
