Systems which requires faster responses of timeout should adjust default configuration for smaller numbers

This helps us to test packages on under a development channel

This package is required to build python with ssl support, probably this should be solved on recipt itself in future

It was removed by mistake

 - use sh -e instead set -e
 - use title instead email when configure re6stnet

  This script still on experimental stage, only works for debian 7.
  The preseed.cfg is a pure netinstall debian automation setup, it
  don't install slapos by itself for now.

In case of vpn, use it.

No need to run slapgrid, as it is run by cron every minute.
Also follows rule of least surprise.

But keep being verbose if it failed.

last command in script may fail, but it is not a problem.

Much easier to debug.

It's not a bug, it's a feature.
