Boaz Leskes f0f89e708d Split cluster state update tasks into roles
This commit splits cluster state update tasks into roles. Those roles
are:
 - task info
 - task configuration
 - task executor
 - task listener

All tasks that have the same executor will be executed in batches. This
removes the need for local batching as was previously in
MetaDataMappingService.

Additionally, this commit reintroduces batching on mapping update calls.
