This change ensures that the nvidia-ctk config default command
generates a config file that is compatible with the official documentation
to, for example, disable cgroups in the NVIDIA Container CLI.
This requires that whitespace around comments is stripped before outputing the
contets.
This also adds an option to load a config and modify it in-place instead. This can
be triggered as a post-install step, for example.

This changes splits the functionality in the internal system package
into two packages: one for dealing with devices and one for dealing
with kernel modules. This removes ambiguity around the meaning of
driver / device roots in each case.
In each case, a root can be specified where device nodes are created
or kernel modules loaded.

This change adds a --create-device-nodes option to the
nvidia-ctk system create-dev-char-symlinks command to create
device nodes. The currently only creates control device nodes.

These changes add a --load-kernel-modules option to the
nvidia-ctk system commands. If specified the NVIDIA kernel modules
(nvidia, nvidia-uvm, and nvidia-modeset) are loaded before any
operations on device nodes are performed.

This change adds an nvidia-container-runtime-hook.path config option
to allow the path used for the prestart hook to be overridden. This
is useful in cases where multiple NVIDIA Container Toolkit installations
are present.

is generated.

This change adds a CLI command to generate a default config.
This config checks the host operating system to apply specific
modifications that were previously captured in static config
files.
These include:
* select /sbin/ldconfig or /sbin/ldconfig.real depending on which exists on the host
* set the user to allow device access on SUSE-based systems

Generate CDI specifications with 644 permissions to allow non-root clients to consume them
See merge request nvidia/container-toolkit/container-toolkit!381
By default, temporary files are created with permissions 600 and
this means that the files created when updating the ldcache are
not readable in non-root containers.

This change adds an nvidia-ctk system create-device-nodes command for
creating NVIDIA device nodes. Currently this is limited to control devices
(nvidia-uvm, nvidia-uvm-tools, nvidia-modeset, nvidiactl).
A --dry-run mode is included for outputing commands that would be executed and
the driver root can be specified.

CDI generation modes such as management and wsl don't require

and replaces it with an instanitation in the nvml CDI spec generation
code.
