Huanxuan Ao 39c5eb9e3f Rename backup commands in volume v1 and v2
Backup commands are used only in volume service now,
but "backup" is too generic, users may not know the
commands are used for volume from the commands name.
By seeing the command name, users can only see the
"backup" but do not know which object the backup
commands work for. It may confuse users. I think
rename "backup" to "volume backup" can depict resource
relation and will be helpful for users to know the
commands clearly.

So add new commands ``volume backup create/delete/
list/show/restore`` to replace the old commands
``backup create/delete/list/show/restore``. And also
deprecate old commands.

Change-Id: I4f844d9bc48573eb4d17288ce6b8a90cea00d16a
Implements: bp backup-snapshot-renamed-for-volume-resource
