[release-4.6] Bug 1896167: Back port HAProxy reload failures alert fix #486

Merged

Conversation

This is the 4.6 backport of #481


openshift/router#209 reworks the HAProxy reload fails metric so that the HAProxyReloadFail alert can
be improved. The new template_router_reload_failure metric in router #209 that replaces the template_router_reload_fails metric is a simple boolean gauge metric, which allows the HAProxyReloadFail alert to fire for the duration of the HAProxy reload outage. Previously, the HAProxyReloadFail alert would fire for ~5 minutes regardless of whether or not reloads were still continuing to fail on the router.
