KAFKA-6134: Read partition reassignment lazily on event handling
This patch prevents an O(n^2) increase in memory utilization during
partition reassignment. Instead of storing the reassigned partitions in the
`PartitionReassignment` object (which is added after ever partition
reassignment), we read the data fresh from ZK when processing the event.
