Closes#2907 from amethystic/kafka-5118_improve_msg__for_failed_startup_with_nonKafka_data
Add new broker config, `group.initial.rebalance.delay.ms`, with a default of 3 seconds.
When a consumer creates a new group, set the group's state to InitialRebalance and delay the rebalance until `min(group.initial.rebalance.delay.ms, rebalanceTimeout)`. As other members join the group further delay the rebalance by `min(group.initial.rebalance.delay.ms, remainingRebalanceTimeout)`. Once `rebalanceTimeout` is hit or no new members join the group within the delay, complete the rebalance.

KAFKA-5028 moves the controller to a single-threaded model, so we would no longer have work interleaved between preferred replica leader election, meaning we don't need to keep its state.
This patch additionally addresses a bug from KAFKA-5028 where it made onPreferredReplicaElection keep the line calling topicDeletionManager.markTopicIneligibleForDeletion but removes the line calling topicDeletionManager.resumeDeletionForTopics

Closes#2840 from apurvam/exactly-once-transactional-clients
The goal of this ticket is to improve controller maintainability by simplifying the controller's concurrency semantics. The controller code has a lot of shared state between several threads using several concurrency primitives. This makes the code hard to reason about.
This ticket proposes we convert the controller to a single-threaded event queue model. We add a new controller thread which processes events held in an event queue. Note that this does not mean we get rid of all threads used by the controller. We merely delegate all work that interacts with controller local state to this single thread. With only a single thread accessing and modifying the controller local state, we no longer need to worry about concurrent access, which means we can get rid of the various concurrency primitives used throughout the controller.
Performance is expected to match existing behavior since the bulk of the existing controller work today already happens sequentially in the ZkClient’s single ZkEventThread.

Closes#2853 from onurkaraman/KAFKA-5069
This PR covers point (2) and point (5) from KAFKA-5036:
**Commit 1:**
2. Currently, we update the leader epoch in epochCache after log append in the follower but before log append in the leader. It would be more consistent to always do this after log append. This also avoids issues related to failure in log append.
5. The constructor of LeaderEpochFileCache has the following:
lock synchronized { ListBuffer(checkpoint.read(): _*) }
But everywhere else uses a read or write lock. We should use consistent locking.
This is a refactor to the way epochs are cached, replacing the code to cache the latest epoch in the LeaderEpochFileCache by reusing the cached value in Partition. There is no functional change.
**Commit 2:**
Adds an assert(epoch >=0) as epochs are written. Refactors tests so they never hit this assert.

Closes#2661 from amethystic/kafka4866_consoleconsumer_ignore_printvalue
Also:
1. FindCoordinator is more general and takes a coordinator_type
so that it can be used for the group and transaction coordinators.
2. Include an error message in FindCoordinatorResponse to make the
errors at the client side more informative. We have just added the
field to the protocol in this PR, a subsequent PR will update the
code to use it.
3. Rename `Errors` names for FindCoordinator to be more generic. This
is a compatible change as the ids remain the same.
4. Since the exception classes for the error codes are in a public
package, we introduce new ones and deprecate the old ones.
The classes were not thrown back to the user (KAFKA-5052 aside),
so this is a compatible change.
5. Update InitPidRequest for transactions. Since this protocol API
was introduced recently and is not used by default, we did not bump
its version.
