Piotr Tabor 6c0e4d97f1 Introduce grpc-1.30+ compatible client/v3/naming API.
This is not yet implementation, just API and tests to be filled
with implementation in next CLs,
tracked by: https://github.com/etcd-io/etcd/issues/12652

We propose here 3 packages:
 - clientv3/naming/endpoints ->
    That is abstraction layer over etcd that allows to write, read &
    watch Endpoints information. It's independent from GRPC API. It hides
    the storage details.

 - clientv3/naming/endpoints/internal ->
    That contains the grpc's compatible Update class to preserve the
    internal JSON mashalling format.

 - clientv3/naming/resolver ->
   That implements the GRPC resolver API, such that etcd can be
   used for connection.Dial in grpc.

Please see the grpc_naming.md document changes & grpcproxy/cluster.go
new integration, to see how the new abstractions work.
