[Log] Add possibility to disable colorization of log outputs

Add setConsoleColor(bool) method to Log module in order to control
colorization on log outputs. Default should be assumed true.
This is useful generally when redirecting outputs or using a
non colorized terminal in order to avoid annoying ANSI escape
sequences.
Add set_console_color(bool) python binding.
Add AIDGE_LOG_COLOR=[off|OFF|0] env var to disable colors at startup.
