  -- Adding the python framework of build and test to inria r2lab pipeline
  -- R2LAB pipeline has logCollections and artifacts storing
  -- Python framework should support latest Rel14 OAI openair-cn/cn-cups EPC
  -- Pipeline uses the latest version of booking-lease script (by duration)
  -- Support for distributed smartphone adb servers
  -- Initial scenarios:
     ** Build on one OAI 4G eNB and one OAI 4G UE
     ** Test in FDD band7 / 5MHz / TM1 in noS1 configuration
     ** Test in FDD band7 / 5MHz / TM1 with latest OpenAir-CN-CUPS --> just attachment

fix phy simulators build Pb: move snr_dB global to simulation code, add a channel mode section in configuration for snr_dB ,add a parameter flag in the config module to allow omitting prefix when modifying a parameter (for compatibility of -s option)

add channel model option to rfsimulator and prevent common libraries re-compilation when using both --UE --eNB options in build_oai script

add config options for rfsimulator, set a common lib for l1sim and rfsimulator, avoid simulation sources to be added twice in some execs (tau.c)
