logging: Add separate logger for health monitoring
Before this patch all logs from the health monitoring part used 'main'
logger. This patch creates a new logger ('health') and health monitoring
parts of code use this logger.

This software tracks health of an embedded device which runs Linux with systemd.
Velia tracks health of systemd units. In case some of them are failing, the system is considered unhealthy. You can disable monitoring of some units by using --systemd-ignore-unit CLI flags. For example, to disable monitoring unit sshd.service you should start velia with --systemd-ignore-unit=sshd.service. In order to disable multiple units use the flag multiple times.
By default, the health of state is shown by flashing certain LEDs. This is however customizable by using your own callbacks.
