Deploys a bifrost container using kolla-ansible bifrost-deploy.

IPA and disk images are downloaded rather than built to improve
reliability.

Currently only minimal testing of the deployment is performed, creating
and deleting an ironic node. Ideally we would perform a bare metal node
deployment.

The job is based on CentOS, as Ubuntu bifrost deployment is currently
failing with a python-MySQLdb error.

cAdvisor (Container Advisor) provides metrics on resource usage and
performance characteristics of running containers.  This change
deploys a cadvisor container and configures prometheus to scrape
data from it.

When enable_ironic_ipxe is set in /etc/kolla/globals.yml,
the following happens:

- a new docker container, ironic_ipxe, is created. This contains
  an apache webserver used to serve up the boot images
- ironic is configured to use ipxe

This patch allows configuration of the Infoblox
pluggable IPAM driver in neutron [0].

When 'infoblox' is chosen as the driver, an Infoblox
IPAM agent can be started as well.  The agent
allows for enhanced DNS capabilities by listening
for neutron and nova notifications.

This feature replaces splitting of compute hosts into inner
and external with a new variable 'neutron_compute_dvr_mode'
that controls whether computes will have full-blown DVR or
internal only (tenant) networking.

We have pin keyston to queens release which supports UUID token through
https://review.openstack.org/546475, let us use UUID in queens and
migrate to fernet in rocky cycle.

This reverts commit df0bf190.

Change-Id: Ifb0112315b5047461ce0bf02c754cc0beac52d9a

we have gates currently broken due using rocky keystone code.
we have no way to test our release until we branch out queens.
this change doesnt change globals default, only our gates tests.

- Ceph images are not being built when using depends-on a kolla build
  job.
- Sync inventory files with current ones which causes ceph to fail due
  missing groups.
- Small corrections in ceph config.yml syntax.
- fix preparse the disk only once
- enable ceph nfs only when enable_ceph_nfs is true

First non-trivial scenario we'll be testing in gates will be cinder +
ceph. This patchset is supposed to create framework to easily add new
testing scenarios.

This patches changes deploy_gate quite a bit so in reality all
deployments will now assume multinode (even if it's single node). After
that we will refactor it even further to enable easy addition of new
scenerios.
