Mark an LTM virtual down when pool in an irule is down.

Hi Alexander, What I am trying to achieve is the opposite of that. We drop the default pool, and the VS goes down, even if the policy has a pool that is passing healthcheck. I just tested this out in the lab on a v13.0.0 HF3 VE and the behavior is consistent with v12.1.2. Hope this helps.

    ltm policy test_policy {
        controls { forwarding }
