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.

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.

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.

Closes#2799 from mjsax/kafka-4990-add-api-stub-config-parameters-request-types
This PR replaces https://github.com/apache/kafka/pull/2743 (just raising from Confluent repo)
This PR describes the addition of Partition Level Leader Epochs to messages in Kafka as a mechanism for fixing some known issues in the replication protocol. Full details can be found here:
[KIP-101 Reference](https://cwiki.apache.org/confluence/display/KAFKA/KIP-101+-+Alter+Replication+Protocol+to+use+Leader+Epoch+rather+than+High+Watermark+for+Truncation)
*The key elements are*:
- Epochs are stamped on messages as they enter the leader.
- Epochs are tracked in both leader and follower in a new checkpoint file.
- A new API allows followers to retrieve the leader's latest offset for a particular epoch.
- The logic for truncating the log, when a replica becomes a follower, has been moved from Partition into the ReplicaFetcherThread
- When partitions are added to the ReplicaFetcherThread they are added in an initialising state. Initialising partitions request leader epochs and then truncate their logs appropriately.
This test provides a good overview of the workflow `EpochDrivenReplicationProtocolAcceptanceTest.shouldFollowLeaderEpochBasicWorkflow()`
The corrupted log use case is covered by the test
`EpochDrivenReplicationProtocolAcceptanceTest.offsetsShouldNotGoBackwards()`

Closes#2794 from ijuma/fix-records-builder-construction
Fixes deadlock scenario found during local test run:
The main thread was waiting for the coordinator lock.
The thread performing close() was holding the
coordinator lock and polling to find coordinator.
The test expected close() to timeout, but for timing
out, the main thread had to update time, which it
couldn't since it was waiting for the lock. This fix
avoids using coordinator in the main thread during
the close task.

In a nutshell: `KafkaStreams` and `StreamThread` are both
waiting for each other since another intermittent `close`
(eg. from a test) comes along also trying to lock on
`KafkaStreams` :
```sh
"main" #1 prio=5 os_prio=0 tid=0x00007f66d000c800 nid=0x78bb in Object.wait() [0x00007f66d7a15000]
java.lang.Thread.State: WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
at java.lang.Thread.join(Thread.java:1249)
- locked <0x000000077d45a590> (a java.lang.Thread)
at org.apache.kafka.streams.KafkaStreams.close(KafkaStreams.java:503)
- locked <0x000000077d335760> (a org.apache.kafka.streams.KafkaStreams)
at org.apache.kafka.streams.KafkaStreams.close(KafkaStreams.java:447)
at org.apache.kafka.streams.KafkaStreamsTest.testCannotStartOnceClosed(KafkaStreamsTest.java:115)
```
=> causing a deadlock.
Fixed this by softer locking on the state change, that guarantees
atomic changes to the state but does not lock on the whole object
(I at least could not find another method that would require more
than atomicly-locked access except for `setState`).
Also qualified the state listeners with their outer-class to make
the whole code-flow around this more readable (having two
interfaces with the same naming for interface and method and then
using them between their two outer classes is crazy hard to read
imo :)).
Easy to reproduced yourself by running
`org.apache.kafka.streams.KafkaStreamsTest` in a loop for a bit
(save yourself some time by running 2-4 in parallel :)). Eventually
it will lock on one of the tests (for me this takes less than 1 min
with 4 parallel runs).

Closes#2791 from original-brownbear/fix-streams-deadlock
This is from the KIP-98 proposal.
The main points of discussion surround the correctness logic, particularly the Log class where incoming entries are validated and duplicates are dropped, and also the producer error handling to ensure that the semantics are sound from the users point of view.
There is some subtlety in the idempotent producer semantics. This patch only guarantees idempotent production upto the point where an error has to be returned to the user. Once we hit a such a non-recoverable error, we can no longer guarantee message ordering nor idempotence without additional logic at the application level.
In particular, if an application wants guaranteed message order without duplicates, then it needs to do the following in the error callback:
1. Close the producer so that no queued batches are sent. This is important for guaranteeing ordering.
2. Read the tail of the log to inspect the last message committed. This is important for avoiding duplicates.
