This PR implements a new partition assignment strategy called "sticky", and it's purpose is to balance partitions across consumers in a way that minimizes moving partitions around, or, in other words, preserves existing partition assignments as much as possible.

Addressed the below review comment from #PR #2998 from mjsax
I am wondering if it would be better, to "embed" the dry-run into the actual code and branch on each place. Otherwise, if things get changed, we could easily introduce bugs (ie, dry run show something different than what the actual reset code does.
We could introduce methods like mabyeSeekToBeginning() that either does the seek or only prints to stdout. This would ensure that the main logic is used to "feed" into dry-run and we don't have code duplication.
WDYT?

The transient failure came from the controller processing the preferred replica leader election
before the restarted broker (the preferred replica leader) has joined isr, causing preferred
replica leader election to fail and for the final zookeeper state validation to fail.

Also disable a couple of tests that were passing incorrectly until KAFKA-3096 is fixed.
The bug was for the following case:
`leader.isDefined && oldLeaderOpt.isEmpty && newLeaderOpt.isDefined && newLeaderOpt.get != leader.get`
We would consider it a successful election even though the new leader was not the expected leader.
I also changed the result type as we never return `None` (we throw an exception instead).

This removes the need to force object initialisation via hacks to register
the relevant Yammer metrics during start-up.
It also works around issues caused by tests that delete JVM-wide singleton
metrics (like `MetricsDuringTopicCreationDeletionTest`). Without this
change, they would never be registered again. After this change, they will
be registered again during KafkaServer start-up.
It would be even better not to rely on JVM side singleton metrics (like we do
for Kafka Metrics), but that's a bigger change that should be considered
separately.

Without the histogram cleanup, the percentiles are calculated
incorrectly after purging of one or more samples: event counts
go out of sync with counts in histogram buckets, and bucket
with lower value gets chosen for the given quantile.
This change adds the necessary histogram cleanup.

* Fix flakiness of `testBrokerTopicMetricsUnregisteredAfterDeletingTopic` by not
consuming messages. Filed KAFKA-5238 to track the issue that metrics for a deleted
topic may be re-created if there are fetch requests in the purgatory.
* Check the log size in `testBrokerTopicMetricsBytesInOut` before attempting to read
the `replicationBytesIn` metric. This helps understand where things have gone wrong
if if the metric has not increased (i.e. if it was an issue replicating or with the metric).
* Only remove the replication bytes in/out if the metrics are defined. This should not
affect the behaviour due to the tags, but it makes the code clearer. We've seen some
cases in Jenkins when the metric does not exist and it's still unclear how that can
happen.

During the 0.11.0.0 cycle, a Java version of the class
was introduced so that Streams could use it. Given that
it includes the bulk of the functionality of the Scala
version of the class, it makes sense to consolidate them.
While doing this, I noticed that one of the tests for
the Java class (`shouldThrowOnInvalidTopicNames`) was
broken as it only checked if the first topic name in
the list was invalid.

This patch adds support for the `TxnOffsetCommitRequest` added in KIP-98. Desired handling for this request is [described here](https://docs.google.com/document/d/11Jqy_GjUGtdXJK94XGsEIK7CP1SnQGdp2eF0wSw9ra8/edit#bookmark=id.55yzhvkppi6m) .
The functionality includes handling the stable state of receiving `TxnOffsetCommitRequests` and materializing results only when the commit marker for the transaction is received. It also handles partition emigration and immigration and rebuilds the required data structures on these events.
Tests are included for all the functionality.
