Upgrade grpc-java to 0.15.0

Posted by liqweed:

Release notes for the versions between the currently supported 0.10.0 and the latest 0.15.0:

Of note:

  • Java 9 & 10 official support
  • Channelz support (proposal/A14-channelz.md at master · grpc/proposal · GitHub). this is important to Java services that consume dgraph via gRPC and also expose gRPC services (as in our use case).
  • Support for Netty Conscrypt.
  • Guava version update (relevant for Guava users).
  • Lots of bug fixes.

Also, since version 0.15.0 Java 6 support was dropped.
