  but directory even does not exist:
    [root@nailgun ~]# ll /var/dump
    ls: cannot access /var/dump: No such file or directory

Steps to reproduce:
  - install cluster by dos.py
  - run 'fuel snapshot'
Expected results:
  - execution finished with no errors
  - snapshot created in /var/dump/
Actual result:
  - execution hangs
  - if to download config by 'fuel snapshot --conf > dump_conf.yaml'
    and adjust timeout field to 120 and run 'fuel snapshot' it fails with:
      [root@nailgun ~]# fuel snapshot < dump_conf.yaml
Generating dump...
