Issue Type: Improvement

[Procedure Framework

framework in HBase (available from HBase 1.1 and up) allows users to build
multi step procedures with built in fault tolerance. The framework was
originally inspired from Fault tolerant executor (FATE) framework from Apache
Accumulo. This is essentially achieved by declaring the procedure as a series
of idempotent execution functions and providing persistence for the result of
each execution. In case of failures, the new owner can first determine the
in-flight procedures and take on its execution. The framework also allows to
build a tree (DAG) of procedures i.e. a procedure can have one or more child
procedures. The next step of procedure will only be executed once all its child
process have successfully completed execution. This can be leveraged by Apache
Phoenix for several of its functions.
I created a doc [Phoenix with
Procedurev2|https://docs.google.com/document/d/1vmaK7Yz7TTbzuBHPR09d4LqtfAj6tkPT0-DjS6nQ6QA/edit]
to consolidate some of the use cases. Please provide comments / ideas to
improve upon it. Also comment on the feasibility vs usefulness of doing it.
