Review Comment:
It looks like the deprecation is now official in the latest grpc-go
releases. They have formally deprecated grpc.Dial and are now recommending
grpc.NewClient as the standard way to create connections. This was finalized
from the PR https://github.com/grpc/grpc-go/pull/7010 we talked about earlier.
