Re: [Kimchi-devel] [PATCH 2/3] Support different "tags" when generating a new name in "get_next_clone_name"

The current implementation of "kimchi.utils.get_next_clone_name" always appends the tag "-clone" in its return values. That may not be suitable for other cases when we want a new resource name without that tag. Add an optional parameter in "get_next_clone_name" so it supports different tags.
