    Delete instance files from dest host in revert-resize
    
    When revert-resize call is finished, it doesn't clear instance
    files from destination node for non-shared instance storage.
    
    The driver call, which is responsible for destroying destination
    host instance is not deleting instance files, because it finds that
    both source and destination host shares the same instance storage.
    
    The check_instance_shared_storage rpc-call had no host information,
    hence the manager call for check_instance_shared_storage was checking
    instance storage on destination host itself and returning True even
    if it is non-shared storage.
    
    Added host parameter to check_instance_shared_storage rpc-call,
    so that in manager call check_instance_shared_storage method get
    executed on source compute node and returns True/False based on
    shared/non-shared storage.
