On Pod definitions gathering, Operator should obfuscate particular environment variables (HTTP_PROXY and HTTPS_PROXY) from containers by default.

Pods from the control plane can have those variables injected from the cluster-wide proxy, and they may contain values as "user:password@[http://6.6.6.6:1234|http://6.6.6.6:1234/]".

1. In order to change deployments, scale down:
  * cluster-version-operator
  * cluster-monitoring-operator
  * prometheus-operator
2. Introduce a new environment variable on alertmanager-main statusSet with either or both HTTP_PROXY, HTTPS_PROXY. Any value but void will do.
4. Run insight-operator to get that pod definitions.
5. Check in the archive (usually config/pod/openshift-monitoring/alertmanager-main-0.json) that target environment variable(s) value is obfuscated.
