Update g3doc for remote gRPC usage

[lampajr]

Hello team,

In recent times, we had the opportunity to experiment with the usage of ml-metadata following the official documentation, specifically focusing on using MLMD with a gRPC server [1].
Initially, based on the examples in the doc currently, we were led to believe users are forced to handle RPC requests/responses, thus requiring a different approach compared to what is shown in the non-gRPC server scenario [2].

After some code investigation, we discovered that it is actually possible to use the MetadataStore by providing it with a MetadataStoreClientConfig as a parameter (with proper MLMD gRPC host and port).
This way, users do not need to manage gRPC requests and responses themselves, unless they have a valid reason to do so.

client_connection_config = metadata_store_pb2.MetadataStoreClientConfig()
client_connection_config.host = 'localhost'
client_connection_config.port = 8080

store = metadata_store.MetadataStore(client_connection_config)

In order to demonstrate its usage, I have created a simple notebook [3] that precisely executes all the steps described in the documentation [2] by making use of a MetadataStore configured with a MetadataStoreClientConfig.

We believe that adding this information to the documentation could be very useful and helpful for all ml-metadata users.

Hope this helps!
