Detect OpenShift version

[rainest]

What this PR does / why we need it:

Adds a draft OpenShift version detection module from telemetry, enables it, and updates some tests for it.

Which issue this PR fixes:

Fix #3149

Special notes for your reviewer:

Relies on Kong/kubernetes-telemetry#168 draft.

Unsure if we want any KIC-level gate before enabling this workflow. We can maybe get a client in the manager setup to check if the chosen namespace exists--if it doesn't, we're presumably not on OpenShift and never will be--but didn't bother for the PoC.
