CI needs for image building

Eventually, if/when TripleO becomes an official Openstack project, all CI for it should be on Openstack systems. Until then we still need CI.

Jenkins

Jenkins from jenkins apt repo.
IRC notification service, notify-only on #triple on freenode, port 7000 ssl.
Github OAuth plugin, permit all from tripleo organisation, and organisation members as service admins.
Grant jenkin builders sudo [may want lxc containers or cloud instances for security isolation]
Jobs to build:

bootstrap VM from-scratch (archive bootstrap.qcow2).

 disk-image-create vm devstack -o bootstrap.qcow2 -a i386

devstack nova-bm execution (archive the resulting image). Chained off of the bootstrap vm build
```
 ssh into the node, run demo/scripts/demo
```

bootstrap VM via image-build chain (archive bm-cloud.qcow2).

 disk-image-create vm glance nova-bm swift mysql haproxy-api \
 haproxy-mysql cinder quantum rabbitmq -o bootstrap-prod.qcow2

baremetal SPOF node build (archive the resulting image).

 disk-image-create mysql haproxy-mysql haproxy-api local-boot \
 rabbitmq -o baremetal-spof.qcow2

baremetal demo node build (archive the resulting image).

 disk-image-create vm glance nova-bm swift cinder quantum \
 -o bootstrap-prod.qcow2

Tempest w/baremetal using libvirt networking as the power API. take a bootstrap baremetal devstack from above, N VM 'bare metal' nodes, and run tempest in that environment.
