Chengyuan Zhang 99993bee13 xds: implement a server interceptor for taking server application metrics and sending to client side in ORCA format (#6018) ... * Added methods in CallMetricRecorder accessor for accessing context key and creating new CallMetricRecorder instance. * Added impl for a server interceptor that records and sends custom metric values to client side. * Added unit test for the server interceptor. * Modified dependencies to have xds package depends on grpc-services (for CallMetricRecorder) and grpc-testing-proto (for testing proto). * Changed usage of GrpcServerRule to GrpcCleanupRule. * make constant fields static * use GrpcCleanupRule to register InProcessChannel to avoid manual shutdown. * Make class public and match the usage of grpclb's load reporting server tracer. * added ExperimentalApi annotation		2019-07-29 14:46:24 -07:00
