[devops] Jenkins runs tests with corrupted (not downloaded completely) iso image

[Artem Panchenko]

This issue was reproduced here:

http://jenkins-product.srt.mirantis.net:8080/job/6.0.ubuntu.promo_bvt/50/consoleFull

Jenkins started system tests with Fuel image that wasn't downloaded completely, md5sum shows that it is corrupt:

original iso on the node where it was built
apanchenko@mc0n1-msk:~$ md5sum /var/www/fuelweb-iso/fuel-6.0-120-2014-11-20_12-44-18.iso
e1367b6bb5032e22e7470559b5d1fd18 /var/www/fuelweb-iso/fuel-6.0-120-2014-11-20_12-44-18.iso

iso, which was given to tests that failed to setup master node
apanchenko@mc2n3-srt:~$ md5sum /home/jenkins/workspace/6.0.ubuntu.promo_bvt/fuel-6.0-120-2014-11-20_12-44-18.iso

I think we can introduce some verification in jobs on CI that Fuel image is downloaded correctly before starting system tests.

It reproduces from time to time and we're working on fix right now.
So high instead of critical.

[Igor Shishkin (teran)]

Wasn't reproduced for last time, but bug is still actual.

[Sergey Kulanov (skulanov)]

The issue appears due to running /usr/bin/seedcleaner.py by CRON:
Please see some latest logs

The proposed patch could fix that problems.
Not changing status to get it for sure.
