* Alerting: Implement GetStatus in the remote Alertmanager struct
* update tests
* fix tests, extract AlertmanagerConfig from PostableConfig
* get the remote AM config instead of the Grafana one from the remote AM
* pass grafana AM config in test
* return error in GetStatus instead of logging it (internal AM)
* Alerting: Persist silence state immediately on Create/Delete
Persists the silence state to the kvstore immediately instead of waiting for the
next maintenance run. This is used after Create/Delete to prevent silences from
being lost when a new Alertmanager is started before the state has persisted.
This can happen, for example, in a rolling deployment scenario.
* Fix test that requires real data
* Don't error if silence state persist fails, maintenance will correct
* Alerting: Add an empty Forked Alertmanager
* Alerting: Add methods for silences to the forked Alertmanager
* check for errors in tests
* make linter happy
* make linter happy
* Alerting: Add methods for silences to the forked Alertmanager
