* 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
* services: implement a lb policy agnostic call metric recorder for backend applications.
* Renamed snapshot() to finalizeAndDump() and make it package-private with an internal accessor class.
* Added Javadoc link for Context.
* Added ExperimentalApi annotation.
* Added since annotations.
* compiler: Use 'SERVICE_NAME' instead of duplicated '$Package$$service_name$'
* compiler: Align indentation
* Fix typo
* Add modified golden files and all re-generated code to meet Travis CI and Windows build requirements
See PR #5943
* Polishing
The `pendingDeadline` variable is modified from the ctor of CancellableContext, but it isn't final. The cancellation can happen before the variable is assigned. It's generally bad practice to leak the this reference from the ctor to other threads anyways.
This code refactors the deadline calculation and scheduling so that `pendingDeadline` is modified under the lock, and the `this` reference is not exposed.
Discovered by TSAN.
ServerCall.close() is meant to only be accessed from a single thread, but in the test it is accessed from the callbacks of several client calls. Synchronize access to sate TSAN.
* Bump PerfMark to 0.17.0
The main changes how linking is done. Linking is now always done
through the `PerfMark` entry class. This is for two reasons:
1. It make instrumenting the linking calls *much* easier.
2. It follows the API pattern of "verbNoun()". Previous callsites
would have `Link link = PerfMark.link(); link.link()`. This
stuttering is not quick to follow.
Generated using:
```
find -name \*.java -exec sed -i 's#link = PerfMark.link();#link = PerfMark.linkOut();#g' {} \;
find -name \*.java -exec sed -i 's#link.link();#PerfMark.linkIn(link);#g' {} \;
find -name \*.java -exec sed -i 's#command.getLink().link();#PerfMark.linkIn(command.getLink());#g' {} \;
find -name \*.java -exec sed -i 's#cmd.getLink().link();#PerfMark.linkIn(cmd.getLink());#g' {} \;
find -name \*.java -exec sed -i 's#msg.getLink().link();#PerfMark.linkIn(msg.getLink());#g' {} \;
```
Since the deprecated link methods are also `@DoNotCall`, the same
sed calls will need to be used on import.
* Fixed LocalityStore test relying on WeightChildPicker list order for mapping to its corresponding locality.
* Fixed bug for not updating new weights for existing localities.
* xds/third_party: import envoy proto based on envoy's commit eefcd0e6fcbeba446454bd5396a34c69348338eb
* xds: fixed breaking changes introduced by changes of fields in ORCA proto message.
In addition to this welcome functionality, this change also makes it
possible to fix http://github.com/bazelbuild/bazel/issues/7157 by
tolerating proto_library rules using a virtual import directory.
The 3rd-party rules_proto project is referencing our compiler directly
and not using our java_grpc_library. This target is fine for them to
use (although we'd prefer using our java_grpc_library), but most users
shouldn't be touching it.

* Cleaned up XdsLoadStatsStore.
- Renamed the StatsStore interface to XdsLoadStatsStore and its corresponding implementation is XdsLoadStatsStoreImpl.
- Revised/reworded specification for XdsLoadStatsStore.
* Cleaned up ClientLoadCounter specification.
Reworded specification for ClientLoadCounter
* Cleaned up XdsLoadReportClient, reworded specifications, formatted tests.
* Removed Xds prefix from LoadStatsStore.
* Removed Xds prefix from XdsLoadReportClient.
In case a negotiating handler misses a read, and it reaches the WBAEH, it should cause a failure. Also, if closing the channel fails while handling another error, log the second failure.
* augmented xds child balancer helper with orcaOobReportingHelperWrapper and added an interface method in LocalityStore for updating out-of-band backend metrics reporting interval
* added an callback for passing load reporting interval received from lrs response to xDS load balancer, thus, LocalityStore for configuring OOB backend metrics reporting
* moved XdsLoadReportCallback interface into XdsLoadReportClient
