Why

To help with investigating 3scale traffic issues in rhoam it would be useful to have access to 3scale metrics like rails_requests_total or apisonator_listener_response_codes

What

based of this investigation https://issues.redhat.com/browse/MGDAPI-5962 enable 3scale metrics in rhoam

How

we need to enable the monitoring stack in 3scale
which we can enable in the apimanger CR

spec: 
  monitoring: 
    enablePrometheusRules: false
    enabled: true

this can be set in the rhoam code base Can be set in the code base here https://github.com/integr8ly/integreatly-operator/blob/rhoam-v1.4.0-rc1/pkg/products/threescale/reconciler.go#L972

• Enabling monitoring will create the Pod monitors in the redhat-rhoam-3scale namespace
• These pod monitors are using the monitoring.coreos.com/v1 but for our monitoring stack we need these resources in monitoring.rhobs/v1

Suggest updating the logic in 3scale-operator to generate both sets of podmonitors
