python alpine image - speed issue

[naiiytom]

Are you considering using python debian-based image instead of alpine-based?
There could be many problems occur according to https://pythonspeed.com/articles/alpine-docker-python/

Suggest to actually measure if there is an issue with speed. Doubling the size on such large docker images would benefit from evidence for a Photon use case. The #174 PR tests failed (maybe mocking the server in tests would be helpful).
