Manage silences without alertmanager

[sfhl]

SUMMARY

Hi there, with the current code it is only possbile to manage silences if any kind of alertmanager(-connection) is available.

If using alerting via grafana only (unified alerting) its not possible to manage silences, because the collection/module uses the /api/alertmanager/grafana/api/v2/silences endpoint.

Hey @sfhl, I'll take a look at this 👍

Hi @sfhl, it should be possible to manage silences with grafana unified alerting and without an external alert manager. The tests of this repository work exactly this way. If you have any further problems on this topic, feel free to re-open this issue again!
