Ronelle Landy 9853d3608f Default private_ipv4 to use public_ipv4 address when null
The static zuul driver returns only a public_ipv4 address for
nodes in use. The multinode bridge role accesses the node
private_ipv4 address. As such, when the private address is
empty/null the role fails.

This review defaults that private address so that the role
uses the public address when the private address is null.
