Remove Py 2 - image size #12

Open dneise opened 4 years ago

I think there are still two Python versions shipped with ACS.

We can do two things to reduce the size if the image.

remove the Py 2 version (probably very simple)
- remove actually both Py versions, which are shipped with ACS .. and use the system python of Centos ...

Also I think ACS installs scipy ... which is not needed by ACS .. but is nice to have for Python developers ...

In my current testing branch https://github.com/dneise/acs_test/tree/2020.6_release I can confirm that Python3 really works.

However I find working with pyenv here really annoying and I wonder if getting rid of all the Python2 in the container would be a good thing.

On the other hand ALMA I guess still has a lot of Py2 sources which they had no time to convert to Py3 yet, so for them removing Py2 would be a killer.
