nixos/gatus: init module

[pizzapim]

Description of changes

In #269477, the Gatus package was added to nixpkgs. I created a NixOS module to run Gatus as a Systemd service. I have been running this myself for a week with no problems. You can see on my personal Git server how this can be used: here I define Gatus endpoints which are services I monitor, and here I configure the service itself.

This is my first contribution to nixpkgs so any comments are greatly appreciated!

I noticed that gatus also supports postgresql as a storage backend, an option for that would be nice, but could also be done in a future PR (and also by someone else, if you don't plan to use it).

none of this is killer so felt iffy for review buuut
mdDoc is pointless and will be removed tree wide eventually anyway.
restart always may be better as unless stopped?
and personal preference not everyone seems to agree with, another inherit for (lib.types) foo bar would be nicer than the using with at all
also why not add yourself as a maintainer?

Indeed, for my use case SQLite is more than enough, so I'd say we can leave this for a future PR of (probably) someone else :) Does seem like a good idea though.

Thanks for all the reviews! Unless there are further comments I think this might be ready for a merge?

[NyCodeGHG]

i have one small thing, would be nice if you could create an extra commit for creating your maintainer in maintainer-list.nix
with the commit message maintainers: add pizzapim, other than that this should be ready to merge :)

[pizzapim]

Done and done!

Hello @pizzapim thanks for the work you put in this PR. What’s left to do before it gets merged?

[NyCodeGHG]

The merge conflict needs to be resolved by rebasing on master, then it should be ready to merge

@drupol, sorry for the ping. The changes you requested have been made.
Could you please have another look. Is there anything else blocking this from being merged?

Isn't this supposed to nixos/doc/manual/release-notes/rl-2411.section.md ?
