This commit refactors `services.grafana.provision.datasources` towards
the RFC42 style. To preserve backwards compatibility, we have to jump
through a ton of hoops, introducing esoteric type signatures and bizarre
structs. The Grafana module definition should hopefully become a lot
cleaner after a release cycle or two once the old configuration style is
completely deprecated.

Allow @resources syscalls in the grafana.service unit. While Grafana
itself does not need them, some plugins (incl. first party) crash if
they fail to setrlimit. This was first seen with the official grafana
Clickhouse datasource plugin.
The @resources syscalls set is fairly harmess anyway.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
adds defaultText for all options that use `cfg.*` values in their
defaults, but only for interpolations with no extra processing (other
than toString where necessary)
If the same plugin appears multiple times in `declarativePlugins`, for
example due to being added both by a module and in user config, the
build fails with an error message similar to
ln: failed to create symbolic link 'grafana-worldmap-panel/glmqcj88zk2bz3mvdr3r7920wxg02qnq-grafana-worldmap-panel-0.3.2': Permission denied
This is solved by removing all duplicates.
