Set resolved GRPC peer hostname

[jbertran]

What does this PR do?

In @grpc/grpc-js 1.1.4, the previously UnimplementedError-raising getPeer() method was implemented correctly. This allows us to retrieve the remote IP of the GRPC server, which was previously not feasible because:

• we didn't have access to the resolved IP through getPeer
• we (still) can't use the address passed in client initialization, as it's not persisted in the client and intercepting it in the constructor is not doable for service clients loaded through @grpc/proto-loader.

Motivation

Plugin Checklist

• Unit tests.
