"important" logging level

[Quantizr]

Adds the "important" logging level for events which need to be in qlogs but aren't errors.
Currently this list is:

• controlsd.initialized
• fingerprinted (forwarded INFO event from carlogger with extra={"important": True} attribute)

Not sure if swaglog.h and logger.h in various submodules should all be updated with the following defines (currently not)

#define CLOUDLOG_WARNING 30
#define CLOUDLOG_IMPORTANT 35
#define CLOUDLOG_ERROR 40
...

#define LOGW(fmt, ...) cloudlog(CLOUDLOG_WARNING, fmt, ## __VA_ARGS__)
#define LOGI(fmt, ...) cloudlog(CLOUDLOG_IMPORTANT, fmt, ## __VA_ARGS__)
#define LOGE(fmt, ...) cloudlog(CLOUDLOG_ERROR, fmt, ## __VA_ARGS__)
...
#define LOGW_100(fmt, ...) cloudlog_rl(2, 100, CLOUDLOG_WARNING, fmt, ## __VA_ARGS__)
#define LOGI_100(fmt, ...) cloudlog_rl(2, 100, CLOUDLOG_IMPORTANT, fmt, ## __VA_ARGS__)
#define LOGE_100(fmt, ...) cloudlog_rl(2, 100, CLOUDLOG_ERROR, fmt, ## __VA_ARGS__)

We have more important logs that aren't necessarily errors, check: fw_versions.py, vin.py. Are these handled?
