director: Added support for backend cluster "tags". This allows using a single director ring for multiple backend clusters. By default everything has an empty tag. A passdb lookup can return "director_tag" field containing the wanted tag name. If there aren't any backend servers with the wanted tag, it's treated the same as if there aren't any backend servers available (= wait for 30 secs for a backend and then return temporary failure). Tags can be added to configuration by adding @tag suffix to IPs/hosts. For example: director_mail_servers = 10.0.0.100-10.0.0.110@name1 10.0.0.120@name2 "doveadm director add" can also add tags either with @tag suffix or with -t parameter. "doveadm director status user@domain" requires giving the user's correct tag with -t parameter or the results won't be correct (empty tag's results are shown). Tags can't currently be changed for an existing host without removing it first.
