Context

When NetObserv introduced their UI loki-operator still didn't provided much information in it's status. Because of this they tried to expand the gateway API but the request was denied. As a result it was suggested for them to use the HTTP endpoint of the query-frontend directly. In a slack thread we discussed that maybe with the advancements in the LokiStack CR the UI should now be able to use it instead of the query-frontend. The goal of this issue is for us to remove the dedicated network policy that we create in the openshift-network tenant to enable this workflow once the team moves to the LokiStack Status (see linked issue)

Acceptance Criteria

• loki-operator stops creating a NetworkPolicy resource that allows ingress to query-frontend in the openshift-network tenant.
• loki-operator should clean up the old resource not just stop creating it.
