Upgrade of repository/packages are moved to Promise
  Introduce hostname promise, for keep hostname == computer_id
  Move messages to logger

 This was a legacy when it was used as script directly

  Still working in progress

  Removal of promise folder is a clean up only. This code should be reworked.

  Move Signature Handling to signature
  Use classes for make easy to testing for mock it
  Introduce Tester (former slapos-test)

Even if it not needed for most of servers.

  It is enough to use @reboot with slapos node boot on cron for include
  approprate minimal start up.

  This can be unconventional for most distros, however it is much more
  simpler and distribution independent.

 This were caused by copy and paste mistake.

 Usage of slapos branch should be only in special cases, no reason to not test against master branch

Compatible with debian/ubuntu/opensuse, it is used to tweak few variables
needed for run KVM or optimize network transference or load some important
modules.

This script is not enabled by default, because it should be used with care.

This script is only supported for OpenSuse and "apt-get types" of Linux.

 This preserve old tapVPN working while upgrade the packages.
