Smart polling interval for Prometheus error calls

This RFE extends https://bugzilla.redhat.com/show_bug.cgi?id=2075575 fix. The issue is that when the Prometheus call returns 404 error, console keeps trying to connect every 5 seconds, which is spamming with errors in Console Logs. Bug was fixed by bumping that interval to 15 seconds. Ideally we should error out if the connection isn't valid, and then wait a duration before trying again, by introducing a smart polling interval that keeps increasing when the calls keep failing.
