CI: deployment of the new container-based strategy

  - Fix in help to allow build within container as root
  - Containers are run in privileged mode to allow "ifconfig up" commands
  - Indirection support and copy to 2nd server
  - Only SPGW-C and SPGW-U cNF are built

  --> Back to where the CI was before interruption
        * Installation of libs
        * Build
        * Configuration
        * Check runs
