control: command line tool to retrieve fan status (set/resume functions)

This is part three of a multipart commit to create a fan control command
line utility to report service status, show target/actual RPM/PWM info,
and manually control single fans. This commit contains the set/resume
commands. Further functionality will come in subsequent commits.

The resume command is a shortcut to start phosphor-fan-control@0 systemd
service, since most workflows require stopping it to allow control of
individual fans. Once manual intervention is done, it can be resumed.

root@p10bmc:~# systemctl stop phosphor-fan-control@0.service
root@p10bmc:~# fanctl resume
root@p10bmc:~# systemctl status phosphor-fan-control@0.service
root@p10bmc:~# <output indicates service is running>

For set/get functions, here is a usage example:

root@p10bmc:~# fanctl set 10000
root@p10bmc:~# fanctl set 2000 fan1 fan3_0
root@p10bmc:~# fanctl get
