Use mlc logger in scripts instead of print statements

[arjunsuresh]

We now have a global logger from MLC being used in Script automation. We need to modify the individual scripts also to use this logger instead of print statements.

@arjunsuresh, do we need to similarly modify all the scripts present inside the script folder individually to replace the print statements with the usage of logger?

[arjunsuresh]

@sujik18 That's correct but a small change is needed. If we initialise logging in each file, they'll log independently which is not desirable. We do have an option to get the global logger in customize.py by doing the following

logger = i['automation'].logger

and then we can do

logger.warning('CM warning: {}'.format(e))

which uses the global logger.
