vpp_config: Rework for Python2/3 compatibility.

On ubuntu:
   $cd <basedir>/extras/vpp_config
   $./scripts/clean.sh
   $./scripts/cp-data.sh
   $sudo apt-get install python3-pip python3-setuptools
   $python3 -m pip install .
   $vpp-config

Changes:
   * Convert to print() function.
   * raw_input changes.
   * floor division changes.
   * replace vpp-config.py with a setuptools 'vpp-config' entry_point.
   * replace netaddr with ipaddress from the standard library and backport.
   * .decode() subprocess.Popen's stdout because in python3 they are bytes.
