Comment 5 for bug 1574591

Yep, Sergey is right, we have to clean repository before each rebuild, because new packages from CRs could have lower versions. But the main issue it that we add new packages to auxiliary repository after bootstrap image is rebuilt:

4. Rebuild bootstrap
```2016-04-25 10:29:23,632 - DEBUG helpers.py:357 -- Executing command: 'fuel-bootstrap build'
2016-04-25 10:34:14,830 - DEBUG ssh_manager.py:201 -- Host: 10.109.1.2
Command: 'fuel-bootstrap build '
Exit code: 0
STDOUT:
Bootstrap image 2f7c8316-626c-4fc5-8fff-2cccc54460a7 has been built: /tmp/2f7c8316-626c-4fc5-8fff-2cccc54460a7.tar.gz```

 9. Deploy the cluster
```2016-04-25 10:37:46,965 - DEBUG ssh_manager.py:201 -- Host: 10.109.1.2
Command: 'chmod 755 /tmp//regenerate_ubuntu_repo'
Exit code: 0
STDOUT:

STDERR:
