    Evalute keystone class before waiting for keystone haproxy backend

    Otherwise may start prematurely and timeout.

Deployment of 1st controller (node-1) failed with this error in puppet log:

http://paste.openstack.org/show/95092/

Events flow http://pastebin.com/A6jWvdzD shows that something went completely wrong with HAproxy backends, many of them had been marked DOWN, so that was a root cause of "504 Gateway Time-out" as well.

Looks like a network connectivity issue at node-1 had caused isolation of node-1:

    Wait for keystone to become ready for floatingip creation

    Wait for keystone service to become ready otherwise
    haproxy reload can lead to haproxy returning
    empty response and thus nova-floating-range provider
    can not authorize with nova.
