      This is a clone of issue OCPBUGS-46150. The following is the description of the original issue:
      —
      If a consumer subscribes to an event using the PTP event api v2, when a new consumer wants to subscribe to the same events it is not possible. A HTTP 409 Conflict response is received by the second consumer and no change events are received.

      Test Steps:

      1. Deploy ptp-operator with v2 event
      2. Deploy a consumer and subscribe to an event
      3. Deploy a second consumer and subscribe to the same event or events.

      Result:
      The first consumer subscribes successfully and here we have a list of available subscriptions. Also the consumer is able to query the PTP event API to check the healthstatus and the currentStates of each subscription.

      Then, deploy another consumer and try to subscribe to the same events. In this case thee logs of the consumer shows that the subscription already exists:

      Note that the requests sent by this consumer (healthckeck and currentstate) are still working.

      Expected Result:
      Two or more consumers can subscribe and receive the same PTP events when there is a change in the PTP operator.
