GPIO Monitor with multiple lines and libgpiod

Added a new GPIO monitor (phosphor-multi-gpio-monitor) which monitors
multiple gpio lines based on their line name or offset. GPIO details
need to be defined in a JSON file and needs to be passed to this daemon.

This uses libgpiod for accessing gpio lines and also uses CLI11 for
parsing input parameter.
