When installing with assisted-installer, ovn_kubernetes takes too much time to bootstrap because it waits for 3rd master

      Original: Description of problem:
      In assisted installer we are using one of the masters as bootstrap and the other 2 masters are becoming the control-plane.  When the 2 master nodes are ready, the 3rd master is installed and becomes the third member of the control plane.
      We noticed that ovn kubernetes is waiting for the 3rd master to join for some time.  Only after the timeout expiration, the installation continues.
      This causes delay in installation time which is undesirable.
      Here are the logs from ovn_kubernetes:

      Steps to Reproduce:
      {code:none}
      1. Install cluster with 3 masters control plane using assisted installer.
      2.
      3.
      

      Actual results:

      
      

      OVN bootstrap takes a long time{code}
      Expected results:

      
      

      Once 2 master nodes are ready, OVN bootstrap should not wait for 3rd master{code}
