Most are not allowed to be zero. Grace period can be zero to immediately
close the connection when the age is hit. A zero permitKeepAliveTime()
simply doesn't enforce any limits on the client.
The choices here precisely matches the pre-existing Netty behavior, but
also seems to make sense in general.
Users appear to be doing `attributes.toString()` to find keys they are
interested in and then unable to find the name of the Key in our API.
They workaround the problem by scanning through `attributes.keys()`
looking for the key of interest. This is an abuse of the keys() API and
unnecessary user friction. They'd happily use the API if they just knew
where to find it.
I added internal to some strings to make it clear that you shouldn't go
looking to use it. There were many strings I didn't change. I focused on
keys most likely to be seen by users, which meant keys in grpc-api and
keys that are available via transport attributes.

JVM startup costs that happen when dependencies are loaded for the
first time can consume a lot of time (we've occasionally observed
around ~5 seconds of CPU time); this causes frequent test flakes
with xds (google-c2p) when using the current 5 second deadline.
Increasing to 15 seconds should give enough time.
Previously examples-xds depended on the normal hello-world, as it used
the same classes. But since b6601ba273 it has had its own classes and
not had a dependency on `:examples.
* xds: Custom LB configs to support UDPA TypeStruct
The legacy com.github.udpa.udpa.type.v1.TypedStruct proto should be supported in addition to the current com.github.udpa.udpa.type.v1.TypedStruct one.

There are still some cases for xdstp processing, but they are to percent
encoding replacement strings. Those seem better to leave running since
it looks like it they could be triggered even with federation disabled
in the bootstrap processing.
Two main incompatibilities existed in the copy of protos in grpc-proto:
no SimpleContext and an Empty method argument was replaced with a
message. "Context" is a very old word for "Metadata" back from the days
before the current gRPC protocol. We don't need that message in
particular, and well-known protos actually works in Protobuf Lite these
days, so we can swap to wrappers.proto's StringValue and don't need to
upstream a change to grpc-proto. The argument problem is fixed just by
changing the type in the Java code.
With the incompatibilities fixed, do a sync from grpc-proto and include
interop-testing.
runUnaryBlockingClosedLoop is failing after 10.3s, which means 5.3s was
probably spent loading the LoadWorker. That means things are likely
indeed slow enough that 5s isn't enough time to wait for the server to
start. A successful execution of runUnaryBlockingClosedLoop takes
12.1 seconds, which again points to general slow execution.
This was observed in the Bazel/Blaze build where io.grpc.util is a
separate target from the rest of core. During the build of a library
SecretRoundRobinLoadBalancerProvider was not on the classpath, and the
library was later included into a binary using grpc-core from Maven
Central which includes SecretRoundRobinLoadBalancerProvider.
```
java.util.ServiceConfigurationError: Provider io.grpc.util.SecretRoundRobinLoadBalancerProvider$Provider could not be instantiated java.lang.ClassCastException: class io.grpc.util.SecretRoundRobinLoadBalancerProvider$Provider cannot be cast to some.app.aaa.aab
```
These APIs were added to NettyServerBuilder for gRFC A8 and A9. They are
important enough that they shouldn't require using the perma-unstable
transport API to access. This change also allows using these methods
with grpc-netty-shaded.
Fixes#8991
Not updating the example WORKSPACE because it doesn't have any
Bazel-enabled build that depends on xds and so doesn't need the
additional repository dependencies.
Fixes#9162
Support for the is_optional logic in Cluster Specifier Plugins:
if unsupported Cluster Specifier Plugin is optional,
don't NACK, and skip any routes that point to it.
WrrLocalityLoadBalancer should remove the locality weights attribute from Resolved addresses after using the information. Not propagating this attribute will make it impossible for another child wrr_locality from working. This is not a supported situation and this change make the failure happen earlier and to be more obvious as to the cause.
remove OrcaOobHelperWrapper layer. Use OrcaOobUtil.updateListener() to set OrcaOobReportListener per each subchannel, not per helper. OrcaOobReportListener is per helper+subchannel unique.
Orca stats are created when creating helper.createSubchannels(), overriding subchannel attributes to store orcaState in the orcaHelper created subchannels
moved orcaMetrics to service project and renamed to MetricRecorder, added internal accessor. Maybe we can combine metricsRecorder and callMetricRecorder, they looks almost the same things.
OrcaServiceImpl depends on metricRecorder, not visa versa.
