[OSSTEST PATCH v9 1/3] ts-openstack-deploy: Deploy OpenStack on a host with devstack

[Anthony PERARD <anthony.perard@citrix.com>]

This script installs any necessary packages and clones all of the OpenStack
trees which are used by devstack to deploy OpenStack.

Signed-off-by: Anthony PERARD <anthony.perard@citrix.com>
Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>

Changes in V9:
- runvars for openstack trees have been renamed to openstack_*
Changes in V8:
- fix job name in sg-run-job
- fix copyright year
- fix too long lines

Changes in V7:
- reindent
- fix style
- remove many workaround, there are not needed anymore.
- create bug report upstream

Changes in V6:
- rebased
- fix issues due to new debian and newer devstack:
  - add missing libvirt group
  - switch back to old nova-network instead of neutron
  - have devstack use 'service' instead of 'systemctl' to restart
    services

Only change in V5:
- edit stackrc from devstack file to change the hardcoded path DEST

No change in V4:
- acked

Change in V3:
- Use host as argument to run the job.
- Use selectjob() and get rid of the unused $gho.
- Use target_jobdir() instead of builddirsprops().
- Remove GIT_BASE from devstack config.
- Rename the script to ts-openstack-deploy (from ts-openstack-devstack).
