- Added support for additional filters when getting webhooks:
- `GET
/api/plugins/grafana-oncall-app/resources/webhooks/?integration=CALBFV7RRDH93`
(filter webhooks that are enabled for the specified integration)
- `GET
/api/plugins/grafana-oncall-app/resources/webhooks/?trigger_type=0`
(filter webhooks with the given trigger type)
- Allow triggering a Manual webhook using an alert group as context:
`POST /api/plugins/grafana-oncall-app/resources/webhooks/<webhook public
ID>/trigger_manual`
Example payload: `{"alert_group": "I4A4I1UPSA7IC"}`
(will return a 200 OK on success)
