  Log Message:
  -----------
  Added global suppor for sharing tags.

The sharing tags (used by cluster-enabled modules to share the actions over same data entity across the whole cluster) are now managed by the clusterer module. The dialog and presence modules will drop their own private implementation.

New module parameter:
* sharing_tag -> tag_name/cluster_is = active/backup
New MI functions:
* clusterer_list_shtags - lists all know sharing tags and their status
* clusterer_shtag_set_active - force a tag to become active on this node

      Functionality will be removed from GitHub.com on January 31st, 2019.
