> Right now, if a pipeline is destroyed by SCM, all the container on the pipeline are marked
as quasi closed when datanode received close container command. SCM while processing these
containers reports, marks these containers as closed once majority of the nodes are available.
> This is however not a sufficient condition in cases where the raft log directory is missing
or corrupted. As the containers will not have all the applied transaction. 
> To solve this problem, we should QUASI_CLOSE the containers in datanode as part of ratis
groupRemove. If a container is in OPEN state in datanode without any active pipeline, it will
be marked as Unhealthy while processing close container command.
