Map common severity values from a Prometheus alert payload
What does this MR do?
This MR adds the ability to map Prometheus specific severity in alert payload located in labels.severity to GitLab alert severity.
Severity Value Mapping
Severity is matched case-insensitive so one can provide CRITICAL or iNfO.
