Bind API interfaces to eth0

Since haproxy is fronting our API endpoints, those should be the only
means to access them.

* Bound glance-api, glance-registry, cinder, keystone, neutron-api, nova api to
  their eth0 interface ip vs *.
* Updated ansible modules to hit the keystone https admin LB endpoint.
* Updated glance api's registry config to use glance registry's https LB
  endpoint.
* Updated setup to open the new glance registry ports.
Updated api-paste to use LB
Updated nova api monitoring

Check via system's eth0 address and not localhost.
