This changes the public api to have a new rpc type, `TapByResource`.
This api supersedes the Tap api. `TapByResource` is richer, more closely
reflecting the proxy's capabilities.
The proxy's Tap api is extended to select over destination labels,
corresponding with those returned by the Destination api.
Now both `Tap` and `TapByResource`'s responses may include destination
labels.
This change avoids breaking backwards compatibility by:
* introducing the new `TapByResource` rpc type, opting not to change Tap
* extending the proxy's Match type with a new, optional, `destination_label` field.
* `TapEvent` is extended with a new, optional, `destination_meta`.
* Make Eos optional in TapEvent
grpc_status not being set in protobuf is the same as being set to zero,
which is also status OK
Modify TapEvent to include an optional EOS struct

* Add Eos to proto & proxy tap end-of-stream events
The proxy now outputs `Eos` instead of `grpc_status` in all end-of-stream tap events. The EOS value is set to `grpc_status_code` when the response ended with a `grpc_status` trailer, `http_reset_code` when the response ended with a reset, and no `Eos` when the response ended gracefully without a `grpc_status` trailer.
This PR updates the proxy. The proto and controller changes are in PR #204.
Part of #198. Closes#202
