Overview of the Issue

vtadmin-api fails to connect to vtgate & vtctld if there are underscores (_) in the cluster ID name. I think this is because gRPC doesn't handle custom name resolvers with _.

Reproduction Steps

Modify clustername in vtadmin-up.sh to a name with underscores:

cluster_name="local_test"

vtadmin-api will fail to connect to vtgate and vtctld.
