All-in-one with nova-network shouldn't bridge lo

[Brent Eagles]

Currently, packstack --allinone sets the *_PRIVIF interfaces to "lo" to add it to to the flat/flatdhcp bridge. Besides being unnecessary, this fails on some systems that do not permit adding the loopback interface to a bridge. Packstack should allow configure the *_PRIVIF interfaces to be empty in the all-in-one case.

    Use dummy interface

    When using nova-network, dummy interface has to be used for Nova private
    interfaces, because otherwice 'lo' interface is being used. Using 'lo'
    is not requirement and it worked on older platform, but does not work
    on CentOS7 and newest Fedora releases during spawning instances following
    error appears:

    TRACE nova.openstack.common.threadgroup NovaException:
    Failed to add interface: can't add lo to bridge br100: Invalid argument
