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?

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.

Closes#2970 from apurvam/KAFKA-5160-broker-side-support-for-txnoffsetcommitrequest
1. Collapsed the `ownedPartitions`, `pendingTxnMap` and the `transactionMetadataCache` into a single in-memory structure, which is a two-layered map: first keyed by the transactionTxnLog, and then valued with the current coordinatorEpoch of that map plus another map keyed by the transactional id.
2. Use `transactionalId` across the modules in transactional coordinator, attach this id with the transactional marker entries.
3. Use two keys: `transactionalId` and `txnLogPartitionId` in the writeMarkerPurgatory as well as passing it along with the TxnMarkerEntry, so that `TransactionMarkerRequestCompletionHandler` can use it to access the two-layered map upon getting responses.
4. Use one queue per `broker-id` and `txnLogPartitionId`. Also when there is a possible update on the end point associated with the `broker-id`, update the Node without clearing the queue but relying on the requests to retry in the next round.
5. Centralize the error handling callback for appending-metadata-to-log and sending-markers-to-brokers in `TransactionStateManager#appendTransactionToLog`, and `TransactionMarkerChannelManager#addTxnMarkersToSend`.
6. Always update the in-memory transaction metadata AFTER the txn log has been appended and replicated, and then double check on the cache to make sure nothing has changed since log appending. The only exception is when initializing the pid for the first time, in which we will put a dummy into the cache but set its pendingState as `Empty` (so it will be valid to transit from `Empty` to `Empty`) so that it can be updated after the log append has completed.
