Functest containers leverage on Python3 instead of python2.
https://mail.python.org/pipermail/python-dev/2018-March/152348.html

It also updates robotframework librairies to latest release and Vmtp
to master ([1] is needed)

It patches cloudify rest client to support python3.

Vmtp is currently disabled because it currently supports python2 only.
