[STORM-3003] Adding Assignment caching to Nimbus
Since nimbus ( scheduler generates assignments) it can cache it instead of
polling for it from ZK or other state manager. This would improve scheduling
iteration time, as well as all UI pages that require assignment information.
The need for this improvement felt when we noticed this is larger clusters
where ZK continues to be bottleneck.
