Switch to python3.7 for engine tox

The base image used for building the docker images used for tox
jobs seem to have switched to python3.7 so this change adapts the
tox script for it.

Please note that the engine itself is still on python3.6 but using
python3.7 for tox shouldn't interfere with it or cause issues.
