> This JIRA is for implementing a daemon thread called StoragePolicySatisfier in namatode,
which scans the asked files blocks which are placed in different storages in DNs than the
related policies specifie. 
>  The idea is:
>       # When user called on some files/dirs to satisfy storage policy, they should have
been tracked in NN and then StoragePolicySatisfier thread will pick one by one file,  then
check the blocks which might have been placed in different storage in DN than what the storage
policy is expecting it to.
>       # After checking all, it should also construct the data structures with the required
information to move a block from one storage to another.
