[pve-devel] [PATCH cluster v11 4/5] datacenter.cfg: add tag rights control to the datacenter config

by adding a 'user-tag-privileges' and 'admin-tags' option.
The first sets the policy by which "normal" users (with
'VM.Config.Options' on the respective guest) can create/delete tags
and the second is a list of tags only settable by 'admins'
('Sys.Modify' on '/')
also add a helper 'get_allowed_tags' that returns the allowed (existing)
tags, the privileged tags, and if a user can enter 'freeform' tags.
