In 48929c4 the protobuf lite artifact name changed from protobuf-lite to
protobuf-javalite. However, the exclusion in grpc-protobuf was missed in the
update, allowing protobuf lite to leak into the classpath. This restores the
previous behavior of only having one protobuf implementation on the classpath.
This would cut the amount of per-thread direct buffer allocations by half, especially with light traffic. This will also cut the amount of file descriptors that's created per thread by half.
Internal benchmark results (median of 5 runs) doesn't show any significant change:
```

grpc-java-java-multi-qps-integrity_only
Actual QPS 711,004 (6,246) 704,372 (6,873)
QPS per Client CPU 23,921 (252) 24,188 (252)

This would reduce the amount of direct buffer allocations, especially with light traffic. This should mitigate internal issue b/143075435
The change is currently optional and is only effective if system property "io.grpc.netty.useCustomAllocator" is set to "true" ignoring the case.

This is a refactor of the existing xds policy to use XdsClient. It does neither create a copy of EDS policy as in #6371 nor re-implement an EDS policy. This should be similar to the idea of https://github.com/grpc/grpc/pull/20368 in C-core.
Here it refactors `XdsComms2` to an implementation of `XdsClient`, which can be drop-in replaced by `XdsClientImp` when it's available.
Let child balancer (currently is Round Robin) handle the address list with only healthy addresses for its locality. If no healthy address available, let the child balancer handleNameResolutionError.
It appears the problem is that server.close() was missing sync(), so the
event loop was still processing the closure when the next test started.
This change is more aggressive than it needs to be, but should make it
less bug-prone.
Fixes#5574
The API review for #6279 came up with a more meaningful name that
better explains the intent. A setter for the old name was left in
ManagedChannelBuilder to ease migration to the new name by current
users.
This change cleans up the definitions of gRPC's data types for envoy's proto messages. These data types carry only information needed for gRPC's logic extracted from envoy's proto messages. Each data type has a static method to convert from its corresponding envoy's proto.
Existing Bootstrapper is an eagerly loaded singleton and reading bootstrap file is done when first time referencing Boostrapper class. This is not use friendly for error propagation.
This change added an instance method Bootstrapper#readBootstrap() for reading the bootstrap file. Instead of making the Bootstrapper instance a singleton, make the bootstrap data (aka, BootstrapInfo) a singleton. Now reading the bootstrap file happens when the first Bootstrapper instance first time calling Bootstrapper#readBootstrap().
Defines an XdsClient interface, which is the blueprint for the class that encapsulates all of the logic for communicating with the xDS server. Also defines watcher interfaces for watching CDS/EDS updates.
