The test previously violated the Kubernetes version skew policy by
deploying a kubelet of hte most recent version in a cluster with an
older apiserver.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Although kubectl has builtin JSONpath support, it is only supported
partially and the support varies between different versions. While using
JSONpath in tests worked for some versions, it failed for others. This
contribution replaces the problematic JSONpath usages with the jq JSON
processor.
The k3s update script filters the assets of a
corresponding release for airgap images archives
and provides these as passthru attributes of the
k3s derivation. We use zstd archives, as these
offer the best compression ratios and decompression
speed. Furthermore, the `airgapImages` passthru
provides the images archive that matches the host
platform architecture, however, this only works
for aarch64 and x86_64. In addition, a txt file
listing all container images of a release is made
available via a passthru attribute. The airgap
images archives can be combined nicely with the
`services.k3s.images` option, e.g. to pre-provision
k3s nodes for environments without Internet
connectivity.
Allow to set kubelet configuration parameters
via an option. Additionally, expose the
respective options for graceful node
shutdown directly, as it is anticipated to
be used frequently.
This contribution extends the k3s module to
enable the usage of Helm charts and container
images in air-gapped environments. Additionally,
the manifests option allows to specify arbitrary
manifests that are deployed by k3s automatically.
It is now possible to deploy Kubernetes workloads
using the k3s module.
Since https://github.com/NixOS/nixpkgs/issues/213943 got fixed, only the main k3s derivation is tested.
Here I changed the tests a bit to make them test all provided k3s derivations

This corrects the multi-node test after a couple recent changes which
resulted in it being broken.
The `lib.toString` change was an incorrect tree-wide refactor, and the
aarch64 change also introduced an error in python indentation/formatting
I believe.
*Flags implies a list
slightly relevant:
> stdenv: start deprecating non-list configureFlags https://github.com/NixOS/nixpkgs/pull/173172
the makeInstalledTests function in `nixos/tests/installed-tests/default.nix` isn't available outside of nixpkgs so
it's not a breaking change
- Replace misleading docs.
- Add new assertions to let configurations make more sense.
- Add clusterInit flag.
- Add some more docs about HA and non-HA modes setup.
- Improve multi-node tests for HA mode.
