    Adds auto-detection for VIP interfaces

    Previously the ctrl plane VIP would default to 'br-ex' which in non-vlan
    deployments ends up being the wrong interface. The public VIP interface
    was also defaulted to 'br-ex' which would be incorrect for vlan based
    deployments. Since a user has already given the nic template (and in
    most cases the subnet that corresponds to the nic) the installer should
    be able to figure out which interface the public/control vip should be
    on.

    These changes enable that type of auto-detection, unless a user
    explicitly overrides the heat parameters for ControlVirtualInterface and
    PublicVirtualInterface. Also removes calling keepalived from haproxy
    now that the services are composed separately on the Controller role.
