Refactor yumdownloader conflicts detection

On the modern OSes (like Ubuntu-13.10 or CentOS-6) the following
commands return nothing:

  yumdownloader -q --resolve ... > yumdownloader.log
  grep "has depsolving problems" yumdownloader.log

Which breaks our conflicts detections mechanism during ISO build.

Add 2-sec sleep between slave nodes start

There are some issues either with iPXE or

PXE booting of virtual slaves. This
workaround makes bootstrapping success

Use lrzip+tar instead of lrzuntar

Extract docker images from archive using lrzip + tar instead of
single lrzuntar command. It should lower extraction times on a
weak hardware.

Also remove each container tarball right after loading it into
docker in order to reduce disk usage.
