[Docs] Is it worth adding some notes on general hosting advice?

There is a lot that can go on with people hosting a bot. I don't think it would be reasonable to walk users through literally every aspect of administering their systems, but as a recent incident showed, even people who have been hosting large public bots for a while may run into some preventable issues for lack of knowing there was a way to prevent them.

In particular, information about setting resource usage limits (and linking out, not fully documenting this per OS) could help prevent certain things like out of memory errors from locking up the host as well, but there are other smaller things that may reasonably fit into this category as well.
