`GracefulSwitchLoadBalancer` was doing switch based on `LoadBalancerProvider.getPolicyName()`. This turned out to be very awkward when I have to synthesize a policy name for the provider, and what I actually care about is the identity of the lb provider not necessarily the policy name.
Now `GracefulSwitchLoadBalancer` is doing switch based on identity of `LoadBalancer.Factory`, which is simpler.
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.
Adds an Executor to NameResolver.Args, which is optionally set on ManagedChannelBuilder. This allows NameResolver implementations to avoid creating their own thread pools if the application already manages its own pools.
Addresses #3703.
This allows plumbing information to the subchannel via Attributes, like
an authority override. RR still does not support multiple EAGs that only
differ by attributes.
This can be used to prevent duplicate classes in the classpath, one via
Maven and one via Bazel-native.

ServerImpl uses that ticker to create incoming Deadlines. This feature is specifically restricted to in-process, as it can also customize ScheduledExecutorService, and them together can fake out the clock which is useful in tests. On the other hand, a fake Ticker won't work with Netty's ScheduledExecutorService.
Also improved mismatch detection, documentation and tests in Deadline.
Fixes#5593 and supersedes #5601
Now that https://github.com/census-instrumentation/opencensus-java/pull/1854 has been merged & released as 0.21.0. We can start using the method & status tags.
Background:
Opencensus introduced new tags for status and method (https://github.com/census-instrumentation/opencensus-java/pull/1115). The old views that used those tags were deprecated and new views were created that used the new tags. However grpc-java wasn't updated to use the new tags due to concern of breaking existing metrics. This resulted in the old views being deprecated while the new views were broken (goomics #50).
https://github.com/census-instrumentation/opencensus-java/pull/1854 added a compatibility layer to opencensus that would remap new tags to old tags for old views. This should unblock grpc to switching to the new tags while allowing old views to still be populated. That commit was released as part of opencensus 0.21, which grpc currently uses
* 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.
