Description of problem:
when deploying with the br-ex provisioning enabled, the puppet on the neutron node failed to resolve. after adding the staypuft server address to resolve.conf, things got fixed. My guess it is because the dhclient replaced the resolv.conf after adding the eth* to the bridge. 

There was a line:
; generated by /usr/sbin/dhclient-script
in the resolv.conf
