libtuning: Migrate prints to python logging framework
In ctt_ccm.py the logging functionality of the Cam object was used. As we don't want to port over that class, it needs to be replaced anyways. While at it, also replace the eprint function as it doesn't add any value over the logging framework and misses the ability for easy log formatting. For nice output formatting add the coloredlogs library.
