Add tags in the response message of outputs.proto

[leodido]

What would you like to be added:

A (repeated) field in the response message output.proto protobuf definition aimed at tagging the outputs that the gRPC output server emits.

Also we probably want the tags field to be in the request message too for filtering.

Why is this needed:

To provide a mechanism to filter/tag output events. Ref #822.
