Inject DRM device nodes into containers when Graphics or Display capabilities are requested
See merge request nvidia/container-toolkit/container-toolkit!235
This change adds the discovery of DRM devices associated with requested
devices. This means that the /dev/dri/card* and /dev/dri/renderD*
devices associated with each requested NVIDIA GPU are injected into
the container and that the /dev/dri/by-path symlinks associated with
these devices are created in the container.

This change adds support for filtering entities by specifying a filter.
This can be used, for example, to check whether a mount or device
has a particular property and removing it from the set of discovered
entities if it does not.

This change adds a Devices abstraction to the CUDA image utilities. This
allows for checking whether a devices is selected, for example.

Add nvidia-ctk hook chmod command to set permissions and ensure permissions of `/dev/nvidia-caps` is set
See merge request nvidia/container-toolkit/container-toolkit!232
This change generates one or more createContainer hooks for ensuring
that subfolders in /dev have the required permissions in the container.
As an example, a user requires read permissions to the /dev/nvidia-caps
in addition to including the specific caps devices under this folder.

This change adds an nvidia-ctk hook chmod command that can be used
to update the permissions for paths in the container.
This prepends the container root to the paths to allow these to be
updated by runtime executables.

This change ensures that the CDI spec mounts the ipc sockets with the
noexec flag to allow these to function in rootless mode with podman.

This change updates the ordering of internal pipeline dependencies to
ensure that the correct rules are applied.

This change includes meta devices (e.g. /dev/nvidiactl) in the
generated CDI spec. Missing device nodes are ignored.

This change generates a v0.4.0 CDI spec instead of a v0.5.0 spec.
This allows older versions of podman, for example, to be used.
This requires that the device names do not start on a numeric character
and that the HostPath for a device is unspecified.

This change allows the swarm-resource config option to specify a
comma-separated list of environment variables instead of a single
environment variable.
The first environment variable matched is considered and other
environment variables are ignored.

This change adds functionality to generate CDI specifications
for all devices detected on the system. A specification containing
all GPUs and MIG devices is generated. All libraries on the host
ldcache that have an NVIDIA Driver Version suffix are included as
are the required binaries and IPC sockets.
A hook (based on the nvidia-ctk hook subcommand) to update the ldcache
in the container for the libraries being injected is also added to the
CDI specificiation.
