Extensive README, a server that exposes channelz and has pauses, and a client that uses multiple channels also exposes channelz service and has a 30 second delay to allow people to run the grpcdebug tool.

This commit uses [OpenCensus Annotation][] to report message size
[bytes] for inbound/received messages in traces.
`addMessageEvent` API which is currently used expects both uncompressed
and compressed message (optional) sizes to be reported at the same.
Since decompression for messages happens at a later point in time,
reporting compressed message as is and reporting uncompressed size as
`-1` renders the size as _0 bytes received_ in cloud tracing front end.
As a workaround, we add _two annotations for each received message_:
* For compressed message size
* For uncompressed message size (when it is available)
This commit also removes `addMessageEvents` a flag introduced in
PR #9485 to temporarily suppress message events for gcp-observability.

Allows using Android's LocalSocket via a Socket adapter. Such an adapter
isn't generally 100% safe, since some methods may not have any effect,
but we know what methods are called by gRPC's okhttp transport and can
update the adapter or the transport as appropriate.
After #9937 was merged, the Java observability tests start to fail.
This System.exit(0) call in the existing Interop client main() method
prevented execution to continue in the new combined Observability
Interop test binary here. (The new binary is calling the old binary's
main() method.)
This is the latest version of the plugin supported by the Gradle version
in use at the moment (7.6).
Note that this also upgrades the R8 optimizer to a version (4.0.48) that
now uses "full mode" optimization by default.
This also splits off Android projects to run under Java 11 (Gradle
plugin requirement) while the other projects continue to run under Java
8.
We will be running this with Java 11, which has elevated some earlier
warnings to errors that fail the build. We don't want the build to fail
because of this.
gcp-observability has many dependencies so is a bit annoying in some
build systems to get working... just for it not to be used in
non-observability scenarios.
grpc-go and c core are using separate binaries for gcp-observability
interop testing, so do the same in Java, which makes interop-testing a
bit lighter.
* In `handleRpcStreamClosed()`, move retry handling to before the call to `xdsResponseHandler.handleStreamClosed()` so that TSan doesn't report a race condition that is completely meaningless.

google-cloud-logging brings in xds, services, and netty-shaded versions
1.43.2. grpc-netty-shaded and xds use internal APIs, so their version
needs to align with grpc-api and grpc-core. OpenCensus stackdriver
components also brings in netty-shaded version 1.27.2, but it was later
in the dependency list so google-cloud-logging's versions won out even
if using Maven.
We don't need an explicit dependency on netty-shaded because xds depends
on it transitively.
This was discovered because our GAE interop test failed in the course of
PR #9858 which added grpc-gcp-observability to interop-testing (and thus
also gae-interop-test):

URI schema are case-insensitive. Previously the code would do
case-sensitive matching. We expect NameResolverProviders to return the
typical canonical scheme formatting, which is lower-case. If a
NameResolverProvider returns an unexpected string (upper case, unicode,
etc), then it simply won't ever match. Channel users, however, can use
either casing in target strings.
The code implicitly already handled relative URIs by returning null, as
Map.get(null) returned null.
When XdsClient learns that a control plane no longer tracks a resource,
it should only notify watchers associated with that control plane.
This matters in control plane federation cases when more than one
control plane is in use.
This change is to address b/269159638 about GCP metadata server returning an unexpected REFUSED status instead of NXDOMAIN. This causes a 15s delay with older versions of systemd-resolved.
This issue was observed with systemd 245.4. Version 251 worked without issue.
* Add new metric views; Register latency and bytes per metrics views for observability
* update view description to inlcude client/server
* Use pre-defined aggregation from OpenCensus for bytes histogram
* updated view names
Introduce an AsyncService interface in the generated code and move the methods from <service>ImplBase to default implementation of the interface.
* update pom files to allow java 1.8
* Add a bindService(<service>Async) method
* Change TestServiceImpl to use the interface and include a bind method instead of extending TestServiceImplBase.
* Correct value being passed to throttler which had been backwards.
* Fix flaky test.
* Add a test using AdaptiveThrottler with a CachingRlsLBClient.
* Address test flakiness.
* Made dependency on build.gradle in protobuf tasks relative so as to make downstream tasks cacheable
* Made transformer cacheable
* Add property name to path to root build.gradle

This change has these main aspects to it:
1. Removal of any name resolution responsibility from ManagedChannelImpl
2. Creation of a new RetryScheduler to own generic retry logic
- Can also be used outside the name resolution context
3. Creation of a new RetryingNameScheduler that can be used to wrap any
polling name resolver to add retry capability
4. A new facility in NameResolver to allow implementations to notify
listeners on the success of name resolution attempts
- RetryingNameScheduler relies on this
