-- Jenkins Pipeline script:
     -- Moved the node to a proper subnetwork
     -- Added ansiColor option
  -- XML testsuite file can now be an option to the main.py python script
     -- Added some examples testsuite templates
  -- main.py python file
     -- Added an option when opening an SSH session: taking care of clients with copied SSH keys
        in that case, verifing that we are on the correct host
     -- BuildeNB method is closer from Fujitsu's original one
        improvement on flexibility for code source path naming
        better clean-up of workspace
     -- LTEBOX EPC (init / termination / logCollection) methods improvements w/ a /tmp path
     -- Checking of processes (EPC / eNB) is parallelized
        also handles LTEBOX EPX vs OAI CN
     -- UE methods added: attach, detach, reboot, ping
        With complete parallelism for multiple UEs
        iperf added but not tested

  -- temporary into a separate jenkins job
  -- parameters are not in the pipeline script file
     they have to be set up manually in the Jenkins GUI configuration page
     they are then check if present in pipeline script
  -- call to python script
     -- build on a server with RF HW capabilities
        for the moment USRP B2x0
        also handles merge request process for gitlab
     -- since it is for CI, it is a clean build
     -- connect to an EPC (OAI or LTEBOX)
     -- terminates eNB / EPC
  -- log collection
