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.

code.

This change generates device folder permission hooks per device instead of
at a spec level. This ensures that the hook is not injected for a device that
does not have any nested device nodes.

This change adds an nvcdi package that exposes a basic API for
CDI spec generation. This is used from the nvidia-ctk cdi generate
command and can be consumed by DRA implementations and the device plugin.
