core (logs): taints:
log taints can be specified using log_levels_taints_dict in sat.conf, where key is a level name, and value is a list of color or code names. For instance, the following conf would taint INFO level in bold/green and DEBUG in default color:
log_levels_taints_dict = {"debug": [], "info": ["green", "bold"]}
Unknown names are copied as raw strings.
