Reload configuration on SIGHUP

[Matt-Deacalion]

I have a shell script that is executed on a uevent from udev. In this script, I have to restart Qtile. At the moment I'm accomplishing this with the following:

echo restart | qshell -s /home/matt/.cache/qtile/qtilesocket.\:0.0 &> /dev/null

This isn't ideal due to the hard coded qtilesocket path. Would it be ok to add the ability to either restart Qtile or reload the configuration file when Qtile receives a SIGHUP, adhering to the Unix convention?

That should be fine to add that functionality and pretty easy with the asyncio signal handlers [1]. In the interim, if you are using the default socket location, you don't need to call qshell with the socket name, also the -c flag can be used to pass in a command.

Reverted in #2257 because of #2256.

I think it would be fine to use SIGUSR1 for this.
