Increase scheduler wait timeout and improve logs collection

In some case, the test node needs more time to pull the
zuul image. This change increases the wait time to 8 minutes
to prevent false positive failure.

Thsi change also:
* adds a build artifact with the generated kubernetes resources.
* redirects post commands output to logfiles to unclutter the
  job-output console.
* replaces kubectl wait by rollout status.
* wait for operator and nodepool-launcher deployment.
