Remove print statements before releasing on PyPi

[jochasinga]

There is current a few places where there are still print statements. Can we switch to logger instead?

print("Setting config file path")

@chester-leung are these print statements save to remove and use logger instead?

[chester-leung]

Yes, we can replace these print statements with log messages. Currently I don't believe there's a logger configured for the tests as a whole though.
