Run the OSA bootstrap in the Zuul pre phase

We will now run the bootstrap-ansible and bootstrap-aio scripts in
the Zuul pre-run job phase. This has several benefits:

- Job stability will be higher. When we occasionally receive nodepool
  instances with unreliable networking, the job will often die off
  during the role clone due to git or pip internet resource
  unavailability. Jobs that fail during pre-run will be retried
  several times by Zuul using different nodes/clouds.

- Jobs which inherit the integrated role's job definition may add
  pre-run playbooks of their own, which allow child jobs to
  configure OSA parameters in /etc/openstack_deploy (such as custom
  user variables or conf.d definitions). Child job pre-run playbooks
  will run after the parent's, so the child job can configure itself
  with the benefit of an already bootstrapped OSA AIO configuration.

- The Zuul pre-run phase runs on a separate timeout from the run
  phase, so our run playbook will have more time available to it
  due to the bootstrapping being done before the run timeout begins.

Environment variables are used to skip the bootstrap scripts when
executing gate-check-commit during the job's run phase.
