> Currently, SCM only persist the pipeline info of a container in container.db upon allocation.
This provides better scalability which offloads the query of container info to datanodes.

> However, this is not enough enough information for SCM to provide shared container service
as other clients may not know the container creation state on datanodes by the creator of
the container. 
> This is the first patch that introduces container states on SCM and ACK message from
creator of the container to update/persist the container state on SCM container store.
