This fix ensures that the default config file path for the nvidia-ctk runtime configure
command is set consistently.

This change updates the create-symlink hook to be equivalent to
ln -f -s target link
This ensures that links are updated even if they exist in the container
being run.

This change updates the create-symlinks hook to always evaluate
link paths in the container's root filesystem. In addition the
executable is updated to return an error if a link could not
be created.

This chagne ensures that we always treat the link path as a path
relative to the container root. Without this change, relative paths
in link paths would result links being created relative to the
current working directory where the hook is executed.

The hostRoot argument is always empty and not applicable to
how links are specified.
Links are specified by the paths in the container filesystem and as such
the only transform required to change the root is a join of the filepath.

Since hostRoot is always the empty string and we are changing the root in the
target path to /, the call to changeRoot is redundant.

This change removes support for specifying csv-filenames when
calling the create-symlinks hook. This is no longer required
as tegra-based systems generate hooks with `--link` arguments.
This also allows the hook to better serve as a reference implementation
for upstream projects wanting to implement a set of standard CDI hooks.

This change allows IMEX channels to be requested using the
volume mount mechanism.
A mount from /dev/null to /var/run/nvidia-container-devices/imex/{{ .ChannelID }}
is equivalent to including {{ .ChannelID }} in the NVIDIA_IMEX_CHANNELS
envvironment variables.

We ensure that we use the same low-level runtimes regardless
of the runtime engine being configured. This ensures consistent

This change refactors the toml config file handlig for runtimes
such as containerd or crio. A toml.Loader is introduced that
encapsulates loading the required file.
This can be extended to allow other mechanisms for loading
loading the current config.

This change adds an include-persistenced-socket flag to the
nvidia-ctk cdi generate command that ensures that a generated
specification includes the nvidia-persistenced socket if present on
the host.
Note that for mangement mode, these sockets are always included
if detected.

This changes skips the injection of the nvidia-persistenced socket by
default.
An include-persistenced-socket feature flag is added to allow the
injection of this socket to be explicitly requested.

This change updates the create-symlinks hook to check whether
link paths resolve in the container's filesystem. In addition

This change ensures that we unnecessarily print warnings for

This change renames the nvidia-ctk system create-device-nodes
flag driver-root to root. This makes it clearer that this is
used to load the kernel modules and is not specific to the
user-mode driver installation.

This change creates an nvidia-cdi-hook binary for implementing
CDI hooks. This allows for these hooks to be separated from the
nvidia-ctk command which may, for example, require libnvidia-ml
to support other functionality.
The nvidia-ctk hook subcommand is maintained as an alias for the
time being to allow for existing CDI specifications referring to
this path to work as expected.

This change adds a features config that allows
