* Alerting: Send alerts to external Alertmanager(s) Within this PR we're adding support for registering or unregistering sending to a set of external alertmanagers. A few of the things that are going are: - Introduce a new table to hold "admin" (either org or global) configuration we can change at runtime. - A new periodic check that polls for this configuration and adjusts the "senders" accordingly. - Introduces a new concept of "senders" that are responsible for shipping the alerts to the external Alertmanager(s). In a nutshell, this is the Prometheus notifier (the one in charge of sending the alert) mapped to a multi-tenant map. There are a few code movements here and there but those are minor, I tried to keep things intact as much as possible so that we could have an easier diff.
