This patch sets DevStack to run in dual stack networking, with both IPv4
and IPv6 networking configured. This change is required for dual stack
testing at the gate.
A different patch was created against devstack-gate to make this the
default, but the Juno branch of Neutron is missing required fixes to the
L3 agent that are present in Kilo. This was the suggested alternative.
