Can we setup the test this way? If you want, you can create another test.
- limit quota to 1 message
- Publish 10 messages
- verify receive times out after first message is received(since quota is full)
- Increase quota to 10
- Verify we receive the remaining 9 messages.

I modified the test a little:
- limit quota to 1
- Publish 1 message and wait for reflecting backlog limitation ※
- Publish 9 messages and verify they will be pended
※ If I produce 10 messages at once in interval of reflecting backlog limitation, they will be sended

@merlimat Do you see any side effect if we rewind it for every exception. All failed pending messages would reach here and invoke rewind.

Rewind is a cheap operation, it just resets the readPosition to markDeletePosition + 1

fixes apache#220 if using `computeIfAbsent `, `consumerManagerFuture.complete(null)` will store in `consumerTopicManagers`, and `getTopicConsumerManager ` will always get future null cache for key which should getTopic again.

Motivation
This closes #199
Modifications
When the replication producer catches an exception,
rewind cursor and continue readMoreEntries (if possible) rather than return immediately.
An unit test for simulating #199 is also added.
Result
Replicator will continue to replicate even when producer exception.
