Feature request: forward logged errors to specific mxid

[matejdro]

(This request is meant for all mautrix bridges but I could not find common base)

Currently, if anything goes wrong with the bridge, error is printed into logs. Unless I'm checking logs regularly, it can be missed easily. If that error causes bridged messages to not be forwarded either way without any indication that things are not okay, it can create pretty annoying problem since people cannot reach me (or vice versa).

So here is an idea: what if admin of the bridge could set up specific mxid (or room ID) in bridge's config that would receive any error messages via Matrix? It wouldn't even need to be transcript of the error, just a notification "hey, something has gone wrong with [bridge name]. Check the logs."
