Kminion doesn't automatically reassign partitions

[timchenko-a]

I use Kminion 2.2.8, topicManagement is enabled.

According to the documentation:

Will reassign partitions to ensure every broker leads at least one partition, and that all partitions' replicas are distributed evenly across the brokers. KMinion tries to assign partitionIDs to brokers that have the same broker id.

In our case some partitions got reassign by CruiseControl during rebalance and they never got reassign back by Kminion.

So half of the partitions ended up on a single broker.

I excluded the topic from rebalancing for the future, but still curious if this is a bug or expected behaviour?

Is this potentially fixed via: #257

The issue was that when adding/removing brokers it would potentially be in a situation where one broker doesn't have any partitions. This should be fixed with this change.
