Could add a parameter for kafka-reassign-partitions script to enable a force reassignment for  partitions from dead brokers.

> In a cluster with 5 broker, replication factor=3, min in sync=2,
> one broker went down 
> A user's app remained of course unaware of that and deleted a topic that (unknowingly) had a replica on the dead broker.
> The topic went in 'pending delete' mode
> The user then tried to recreate the topic - which failed, so his app was left stuck - no working topic and no ability to create one.
> The reassignment tool fails to move the replica out of the dead broker - specifically because the broker with the partition replica to move is dead :-)
> Incidentally the confluent-rebalancer docs say
> http://docs.confluent.io/current/kafka/post-deployment.html#scaling-the-cluster
> > Supports moving partitions away from dead brokers
> It'd be nice to similarly improve the opensource reassignment tool
