    Add vip_type to ip_addrs table

    This is to allow assigning of multiple VIPs to a network (currently it is
    necessary to also assign vrouter_vip for public and management networks).

    Implements Blueprint virtual-router-for-env-nodes

    Make vip_type in ip_addrs extendable for new types

    Change vip assigment logic in openstack.yaml.
    Instead of:
    assign_vip = True (haproxy by default)
    assign_vrouter_vip = True
    we have:
    vips = ["haproxy", "vrouter"] (when we want to assign VIP
    for haproxy and vrouter) or just do not provide 'vips' parameter
    (when we don't want VIP at all).
