control: command line tool to retrieve fan status (reload function)

This creates a fan control command line utility to report service status,
show target/actual RPM/PWM info, report present/functional status as
retrieved from D-Bus (or "Unknown" if not supported), and set target
RPM/PWM speeds for one or more fans. A "reload" command restarts the fan
control service to allow reload of configuration files. Note: reload
is only available for JSON-enabled configuration, YAML-based systems
emit an error when reload is run.

sample output:

root@p10bmc:~# fanctl status
Fan Control Service State   : loaded, inactive(dead)
CurrentBMCState     : xyz.openbmc_project.State.BMC.BMCState.Ready
CurrentPowerState   : xyz.openbmc_project.State.Chassis.PowerState.Off
CurrentHostState    : xyz.openbmc_project.State.Host.HostState.Off
