move from macro install-chefdk to chef-bootstrap

* removed macro 'install-chefdk' in favor of 'chef-bootstrap'
* macro 'chef-bootstrap' executes a cookbook specific bootstrap
  scipt which preconfigures the testnode (install packages and
  dependencies) before running the tests from the Rakefile with the job
  template 'gate-{name}-chef-rake'
* currently the bootstrap.sh does not exist in all cookbooks, since this
  is a experimental job and the final bootstrap.sh will be defined after
  this patch is merged and then cloned/added to all cookbooks using this
  job
