Allow skipping autopause/autostop using a file

[Steveplays28]

I've added a check to the autopause/autostop daemons to see if the /data/.skip-pause (/data/.skip-stop for autostop) file is present, and if so, prevent autopausing/autostopping.

I've also added notes about this to the docs.

Thanks! Theme of my comments is "keep it simple" 😀.

I implemented your suggestions, and added some brackets and fi statements I missed.
Let me know if anything else needs changing!

Overall, I was wondering if you have been able to test the changes?

[Steveplays28]

At the moment I haven't tested this yet. I can try cloning it onto my homeserver and see if it works.
It'll probably take quite a while to build though.

EDIT: wasn't as bad as I thought. It seems to be posting a log message every 5 ish seconds though:

And it seems like the text isn't quite correct, let me fix that.
Not sure what/if I should do anything about the log message being repeated. Maybe something with the states?
I'll incorporate your review's suggestions first and see if the issue is still present then.

After the latest commit it now looks like this:

The log message is being sent every 10 seconds or so.
It does still go between saying skipping pausing and clients disconnected, pausing in 1200 seconds, which seems a little confusing to me.

Maybe the server should go into stopped state once the check in knocked state detects the file, and the log message shouldn't be printed on init, instead only checking if the other pausing message should be sent. Then the log wouldn't be spammed and the message wouldn't be posted twice on startup.

Test failures were upstream Modrinth 500 errors, so this is good to merge.

Alright, thanks for the reviews and merge!
