      * Previously, the `spec.noProxy` field from the cluster-wide proxy was not considered when the {cmo-first} configured proxy capabilities for a Prometheus remote write endpoint. With this release, the {cmo-short} no longer configures proxy capabilities for any remote write endpoints whose URL would bypass the proxy according to the `noProxy` field.

      Description of problem:

      The cluster-wide proxy is getting injected for remote-write config automatically but not the noProxy URLs in Prometheus k8s CR which is available in openshift-monitoring project which is expected. However, if the remote-write endpoint is in noProxy region, then metrics are not transferred.

      Version-Release number of selected component (if applicable):

      RHOCP 4.16.4

      How reproducible:

      100%

      Steps to Reproduce:

      1. Configure proxy custom resource in RHOCP 4.16.4 cluster
2. Create cluster-monitoring-config configmap in openshift-monitoring project
3. Inject remote-write config (without specifically configuring proxy for remote-write)
4. After saving the modification in  cluster-monitoring-config configmap, check the remoteWrite config in Prometheus k8s CR. Now it contains the proxyUrl but NOT the noProxy URL(referenced from cluster proxy). Example snippet:
==============
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
[...]
  name: k8s
  namespace: openshift-monitoring
spec:
[...]
  remoteWrite:
  - proxyUrl: http://proxy.abc.com:8080     <<<<<====== Injected Automatically but there is no noProxy URL.
    url: http://test-remotewrite.test.svc.cluster.local:9090
   

      Actual results:

      The proxy URL from proxy CR is getting injected in Prometheus k8s CR automatically when configuring remoteWrite but it doesn't have noProxy inherited from cluster proxy resource.

      Expected results:

      The noProxy URL should get injected in Prometheus k8s CR as well.
