Improved image building & new PROX
Bug fixes for the script for building an image via the packer tool. This also installs a newer version of PROX with some bug fixes in PROX. The *.test files have been simplified. Also introduced a new file MachineMap.cfg to map test machines on actual VMs. Change-Id: I69445327ef0a907bc8c1566aaa60c733418c541e Signed-off-by: Luc Provoost <luc.provoost@intel.com>
