I'd disabled Telemetry for the bulk of the CI fleet in OTA-740. But that lead to many
failures for:

[sig-instrumentation] Prometheus when installed on the cluster should report telemetry if a cloud.openshift.com token is present [Late] [Skipped:Disconnected] [Suite:openshift/conformance/parallel]

We should extend the checks for Telemetry enablement to include telemeterClient.enabled in the monitoring-specific ConfigMap, as well as the previously-checked pull-secret token.
