Add support for deleting messages across bridges.
Currently fully support mattermost,slack and discord. Message deleted on the bridge or received from other bridges will be deleted. Partially support for Gitter. Gitter bridge will delete messages received from other bridges. But if you delete a message on gitter, this deletion will not be sent to other bridges (this is a gitter API limitation, it doesn't propogate edits or deletes via the API)
