Upgrades, fix for repo path for host system upgrader

* in 5.0.1 to run host system upgrader
  we used repository which was in upgrade
  tar ball, after upgrade user could delete
  the repo with all temporary data, as
  result user can get broken repository
  which leads to the error during puppet
  run, add hook to fix repo path for 5.0.1
  version
* copy directory with centos repository
  on host system upgrade stage, it helps
  to keep our engines separated from each
  other and user won't have problems with
  removed repository
