Update the Alertmanager routes to DMS for partitioned Prometheus instances in gprd
Issue: https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/16050
This is adding a matcher on the Prometheus instance name for the routes to DMS so that we get a separate DMS snitch for each instance in gprd
.
The additional snitches have been created in DMS and I will update ALERTMANAGER_SECRETS_FILE
in https://ops.gitlab.net/gitlab-com/runbooks/-/settings/ci_cd before merging.
Note: I have also added snitches for the gstg
zonal clusters, which were missing until now.
