qa/suites/cephadm/smb: add new test case for remote control grpc

We recently added testing for the remote control service via the
local unix socket but had no coverage for the gRPC based
mode of operation. This adds a test case that configures and deploys
the needed TLS certs and sets up and tests remote control with gRPC.

Fixes: https://tracker.ceph.com/issues/76676
