public async bool rename_group_async (string old_name, string new_name) throws Error
Rename the given old_name.
On protocols where groups behave like tags, this is an API short-cut for adding all of the group's members to a group with the new name, then removing the old group.
For this to work properly this must have interface IFACE_CONNECTION_INTERFACE_CONTACT_GROUPS.
