/***************************************************************************
*
* The VolumeActionCommand class is used to send commands which apply
* to a particular volume.
*
* The following commands would fit into this category:
*
*   volume mount <volname>
*   volume unmount <volname> [force]
*   volume format <volname>
*   volume share <volname> <method>
*   volume unshare <volname> <method>
*   volume shared <volname> <method>
*
* A typical response looks like:
*
*   # vdc volume unshare sdcard ums
*   605 Volume sdcard /mnt/sdcard state changed from 7 (Shared-Unmounted) to 1 (Idle-Unmounted)
*   200 volume operation succeeded
*
*   Note that the 600 series of responses are considered unsolicited and
*   are dealt with directly by the VolumeManager. This command will only
*   see the terminating response code (200 in the example above).
*
