Static inventory autogeneration (#550)

* At the provisioning stage, allow users to auto-generate a static
  inventory w/o manual steps needed. The alternative to
  go fully dynamic TBD.
* Move openshift pre-install playbook to the post provision playbook,
  where the second part of the pre install tasks is already placed.
