This version works around a warning about DuplicateStrategy in Gradle 6
that will be an error in Gradle 7 caused by [a bug in the plugin][1].
Bumping the version makes a clean build with `--warning-mode all` (at
least if skipping Android and codegen).

I didn't touch Protobuf and Netty; we upgrade those individually. Below
are issues I encountered that caused me to not upgrade (further).
Guava 30.1-android fails to build with Android without enabling
desugaring. https://github.com/google/guava/issues/5358
Robolectric 4.4 breaks AndroidChannelBuilderTest.

Opencensus 0.28.1+ is incompatible with gRPC.

Truth now defines the asm dependency as "compile" although it is still
optional. But asm appears to have accidentally included incorrect gradle
module metadata in their release (I see they've disabled the metadata on
master) which make gradle think it requires Java 8. We could asm
everywhere, but that's is annoying. It seems likely this will resolve
itself.
Mockito can be upgraded to 3.4.0, but it deprecates initMocks, which
causes more code churn than I wanted in this commit. I still
synchronized the example versions on 3.4.0, though, as it was already
being used in some examples and the examples don't use initMocks.
Updated protobuf gradle plugin version to 0.8.13. Fixed Android Kokoro's memory issue by forcing to use a new Gradle daemon for building the previous commit.
javax.annotation-api is licensed CDDL, which was not noticed when it was
introduced. Tomcat provides an Apache 2 version of the same annotation. Note
that this annotation is only used when compiling with Java 9+.
Unfortunately this may cause classpath collisions since there are _many_ copies
of this annotation on Maven Central; we wanted one canonical source and
javax.annotation-api seemed like that source. We hope this won't impact many
users since we have always suggested using it only for compilation. But it will
probably impact some users. However, we didn't create this mess, this seems to
be "standard practice" for J2EE, which this annotation is now part of, so we're
just impacted by it.
Fixes#6833
