Enable gprc-go debug log messages with GRPC_GO_LOG_SEVERITY_LEVEL
https://github.com/grpc/grpc-go#how-to-turn-on-logging mentions that
the GRPC_GO_LOG_SEVERITY_LEVEL
environment variable can be set to enable gRPC debugging, but it
was not possible to enable this previously. The log level was always
overriden because it was too chatty.
To debug gitlab#297359 (closed), we'll need to be able to see the gprc-go logs for both Gitaly and Praefect.
