Pull in guava 22.0 by using the shaded version up in new hbase-thirdparty project.
In poms, exclude guava everywhere except on hadoop-common. Do this so
we minimize transitive includes. hadoop-common is needed because hadoop
Configuration uses guava doing preconditions.
Everywhere we used guava, instead use shaded so fix a load of imports.
Stopwatch API changed as did hashing and toStringHelper which is now
in MoreObjects class. Otherwise, minimal changes to come up on 22.0
Added metrics for RecoverableZooKeeper related to specific exceptions,
total failed ZooKeeper API calls and latency histograms for read,
write and sync operations. Also added unit tests for the same. Added
service provider for the ZooKeeper metrics implementation inside the
hadoop compatibility module.
