Subject: [PATCH] saveconfig: way for block-level save with delete command

currently, we can use block-level save feature for create command and
reconfig of different attributes, but there is no way to use block-level
feature for delete command.

This patch introduces 'save' flag (False on default), which can trigger
saveconfig internally as part of delete command.

$ targetcli /backstores/user:glfs delete test save=True
Deleted storage object test.
