Wildcard or regex in "receivers.keep"?

[soostdijck]

I'm using Victoria Metrics' VMAlertmanagerConfig which get merged into a giant Alertman config. I don't know what other teams are setting up for routing, but it ends up that my receiver is called something like monitoring-ops-alertmanager-config-karma

I would love to be able to regex the receiver filter to make my life easier.

      receivers:
        keep: [ .*karma ]
        strip: []

At the moment I'm seeing duplicates in the UI, or I have to keep adding receivers from various teams as needed.
