Extend volume import functionality to support 'iso', 'snippets',
'vztmpl', and 'import' types, in addition to the existing support for
'images' and 'rootdir'. This is a prerequisite for the ability to move
ISOs, snippets and container templates between nodes.
Existing behavior for importing VM disks and container volumes remains
unchanged.
