* fix suggestions

This commit exposes the low-level gRPC client on the
high level client, for two purposes:

- Allow access to the underlying gRPC channel. This may be useful for capturing properties
  about the channel e.g. the channel authority, for metrics.
- Allow access to the gRPC client to make requests using the low-level gRPC
  client in cases where functionality may not yet be exposed by the higher level client.

* v1.9.0
