    NSX-mh: Failover controller connections on socket failures

    Upon a socket connection failure, release the current connection
    and acquire a new one to a different controller.
    This is achieved by treating socket connection failures as 503
    errors returned by the controller.

    Also, ensure an even distribution of initial connection priorities
    across controllers.
