As a developer I want to support sending of metrics from OpenShift clusters to Red Hat premises for Telemeter by allowlisting metrics on the server side

Description:

As described in the Metrics to be sent via telemetry section of the Design Doc, the following metrics is needed to be sent from OpenShift cluster to Red Hat premises:

• Minimum Routes per Shard
  • Recording Rule – cluster:route_metrics_controller_routes_per_shard:min  : min(route_metrics_controller_routes_per_shard)
  • Gives the minimum value of Routes per Shard.
• Maximum Routes per Shard
  • Recording Rule – cluster:route_metrics_controller_routes_per_shard:max  : max(route_metrics_controller_routes_per_shard)
  • Gives the maximum value of Routes per Shard.
• Average Routes per Shard
  • Recording Rule – cluster:route_metrics_controller_routes_per_shard:avg  : avg(route_metrics_controller_routes_per_shard)
  • Gives the average value of Routes per Shard.
• Median Routes per Shard
  • Recording Rule – cluster:route_metrics_controller_routes_per_shard:median  : quantile(0.5, route_metrics_controller_routes_per_shard)
  • Gives the median value of Routes per Shard.
• Number of Routes summed by TLS Termination type
  • Recording Rule – cluster:openshift_route_info:tls_termination:sum : sum (openshift_route_info) by (tls_termination)
  • Gives the number of Routes for each tls_termination value. The possible values for tls_termination are edge, passthrough and reencrypt. 

The metrics should be allowlisted on the server side.

The steps described in Sending metrics via telemetry are needed to be followed. Specifically step 6.

Depends on CFE-478 and CFE-551.

Acceptance Criteria:

• Support for sending the above mentioned metrics from OpenShift clusters to the Red Hat premises by allowlisting metrics on the server side
