Procedure v2 (aka Notification Bus) aims to provide a unified way to build:
* multi-steps procedure with a rollback/rollforward ability in case of failure (e.g. create/delete table)
** HBASE-12070
* notifications across multiple machines (e.g. ACLs/Labels/Quotas cache updates)
** Make sure that every machine has the grant/revoke/label
** Enforce "space limit" quota across the namespace
** HBASE-10295 eliminate permanent replication zk node
* procedures across multiple machines (e.g. Snapshots)
* coordinated long-running procedures (e.g. compactions, splits, ...)
* Synchronous calls, with the ability to see the state/result in case of failure.
** HBASE-11608 sync split
still work in progress/initial prototype: https://reviews.apache.org/r/27703/
