MSuite is not using kbase/sdkbase2:python docker image

[ialarmedalien]

Changelog states the following for v1.4.0:

updated KBase Docker base image to sdkbase2:python and added Cython lib fix

However, the docker base image is still stuck on kbase/kbase:sdkbase2.latest, and attempts to build the image fail with EOL warnings about python 2.7.

I started experimenting with moving over to sdkbase2:python, but other errors started cropping up. I had also assumed that the code was in python 3, but that is not the case.

CheckM is in python 2. we're still waiting for a python 3 version. it may never happen.

CheckM has been updated to python 3 - hurrah! They have removed the bin_qa_plot function so the kbase app will need to be updated accordingly. There may be other changes -- I didn't delve deeper into the release notes.
