nixos/httpd: extraSubservices cleanup

[aanderse]

Motivation for this change

services.httpd.extraSubservices is marked as deprecated so removing some of the final remnants of it.

@vcunat what did you want to do with the btmantis module? Should be pretty straight forward to change it into a full module like I've done with limesurvey, mediawiki, wordpress, etc... but if I'm going to do that I'd like to make sure there is someone to list as a maintainer (while I'm happy to rewrite the module if desired I'm not offering to be a maintainer 😄). The other option would be to drop it because it isn't being maintained. Please let me know what you'd like.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

btmantis: from my point of view it was a one-time experiment, and I haven't really used it. Theoretically, @tohl might be interested, but it seems more likely that noone will be.

@vcunat thanks for the clarification. We'll let this stew a few days and then merge unless @tohl says otherwise I guess then.

i have no use for btmantis anymore so this can be removed thanks and sorry for the delay

[aanderse]

@tohl no problem, thanks!
@vcunat looking to you for final review and merge if you have the time.

Better not me. I'm relatively scarce on time, and my involvement with http services has been almost non-existent, so I'll prefer working on other nixpkgs stuff.

👍 on removing unmaintained cruft!

I would like us to consider what we can do about making web services more generic.

I have a feeling all Python applications using wsgi could be abstracted in a way that allows the end user of the module to plug it into any web server that supports the wsgi protocol.

The same goes for cgi, reverse proxies and so on.

@adisbladis one thought I had was that the nginx module has some large advantages over httpd in that the virtualHosts option in nginx is an attribute set and httpd is stuck with a list. If httpd and nginx module options were made more similar (or at least compatible) I think that's one way to make web services more generic (though not the only way).

I'm planning on putting in a PR to migrate the services.httpd.virtualHosts to an attribute set like nginx, and possibly some other changes to make the two option sets more similar. Let me know if you're interested in that possible PR, or if you have a better idea for making web services more generic as that is a topic I'm quite interested in.
