The gated modifiers used to add support for GDS, Mofed, and CUDA Forward Comatibility
only check the NVIDIA_VISIBLE_DEVICES envvar to determine whether GPUs are requested
and modifications should be made. This means that use cases where volume mounts are
used to request devices are not supported.
This change ensures that device extraction is consistent for all use cases.

This change adds an nvidia-container-runtime.modes.legacy.cuda-compat-mode
config option. This can be set to one of four values:
* ldconfig (default): the --cuda-compat-mode=ldconfig flag is passed to the nvidia-container-cli
* mount: the --cuda-compat-mode=mount flag is passed to the nvidia-conainer-cli
* disabled: the --cuda-compat-mode=disabled flag is passed to the nvidia-container-cli
* hook: the --cuda-compat-mode=disabled flag is passed to the nvidia-container-cli AND the
enable-cuda-compat hook is used to provide forward compatibility.
Note that the disable-cuda-compat-lib-hook feature flag will prevent the enable-cuda-compat
hook from being used. This change also means that the allow-cuda-compat-libs-from-container
feature flag no longer has any effect.

This change adds the enable-cuda-compat hook to the incomming OCI runtime spec
if the allow-cuda-compat-libs-from-container feature flag is not enabled.
An update-ldcache hook is also injected to ensure that the required folders
are processed.

This change REMOVES the ability to set opt-in features
(e.g. GDS, MOFED, GDRCOPY) in the config file. The existing
per-container envvars are unaffected.

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 adds a features config that allows
individual features to be toggled at a global level. Each feature can (by default)
be controlled by an environment variable.
The GDS, MOFED, NVSWITCH, and GDRCOPY features are examples of such features.

This change adds support for an NVIDIA_NVSWITCH environment variable.
When set to `enabled` this striggers the injection of all available
/dev/nvidia-nvswitch* device nodes.
