Prometheus3 custom_rules hardcoded to prometheus2 path #580
Description
The reference for where the custom_rules is hardcode in https://github.com/cloudfoundry/prometheus-boshrelease/blob/master/jobs/prometheus/templates/config/prometheus.yml#L27 to point to /var/vcap/jobs/prometheus2/config/custom.rules.yml but should probably be /var/vcap/jobs/prometheus/config/custom.rules.yml now that the job has been renamed from prometheus2 to prometheus.
The release currently renders the file correctly to /var/vcap/jobs/prometheus/config/custom.rules.yml but the config doesn't use this file.
I can make a PR if desired but didn't know if there was something else in flight or if this was somehow the desired state.
