Try to match unknown failures associated with a machine when we update the tags of that machine
What?
When we change machine's tags (especially add a new one) we should try to match all unknown failures associated with that machine with the updated set of filters (some filters are tied to tags).
Why?
Sometime we are late with adding tags after changing machine configuration which leaves us with a bunch of unknown failures. Currently there is no way of matching them in automated way after updating the tags.
