-------------------------------------
    Description: 
If a partition of a topic with idempotent producer has no data on 1 of the 
brokers, but it does exist on others and some of the segments for this 
partition have been already deleted replication thread responsible for this 
partition on the broker which has no data for it fails to start with out of 
order sequence exception:

{code}
We run kafka 0.11.0.1 and we ran into the situation when 1 of replication 
threads was stopped for few days, while everything else on that broker was 
functional. This is our staging cluster and retention is less than a day, so 
everything for partitions for which replication thread was down was cleaned up. 
At the moment we have a broker which cannot start replication for few 
partitions. I was also able to reproduce in my local test environment.
Another possible use case when this might cause real pain is disk failure or 
any situation when previously deleting all the data for the partition on a 
broker helped - since it would just fetch all the data from other replicas. Now 
it does not work for topics with idempotent producers. It might also affect 
other not-idempotent topics if those are unlucky to share same replication 
fetcher thread. 

This seems to be caused by this logic: 
https://github.com/apache/kafka/blob/0.11.0.1/core/src/main/scala/kafka/log/ProducerStateManager.scala#L119

and might be fixed in the scope of 
https://issues.apache.org/jira/browse/KAFKA-5793.

However any hints on how to get those partition to fully replicated state are 
highly appreciated.
