This change enables opt-in (off-by-default) features to be opted into.
These features can be toggled by name by specifying the (repeated)
--opt-in-features command line argument or as a comma-separated list
in the NVIDIA_CONTAINER_TOOLKIT_OPT_IN_FEATURES environment variable.

[no-relnote] Get low-level runtimes consistently
We ensure that we use the same low-level runtimes regardless
of the runtime engine being configured. This ensures consistent
behaviour.

This change converts the toolkit installation logic to a go package
and invokes this installation over the go API instead of starting
this executable.

This change makes the following changes:
* Allows the toolkit.pid path to be specified
* Creates the toolkit.pid file at /run/nvidia/toolkit/toolkit.pid by default
* Handles failures to remove the /run/nvidia/toolkit folder

This changes adds an option to the toolkit container to allow
the dev root to be specified. This adds support for driver installations
where the driver files are at one root and the dev nodes are created
elsewhere -- most typically at /. This is the case, for example, for
GKE driver installations.

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 --create-device-nodes option to the toolkit config CLI.
Most noteably, this allows the creation of control devices to be skipped
when CDI spec generation is enabled.
Currently values of "", "node", and "control" are supported and can be set
via the command line flag or the CREATE_DEVICE_NODES environment variable.
The default value of CREATE_DEVICE_NODES=control will trigger the creation
of control device nodes. Setting this envvar to include the (comma-separated)
strings of "" or "none" will disable device node creation regardless of
whether other supported strings are included.

This change renames the root transformer to indicate that it
operates on host paths and adds a container root transformer for
explicitly transforming container roots.
The transform.NewRootTransformer constructor still exists, but has
been marked as deprecated.

Instead of relying solely on a static config, we resolve the path
to ldconfig. The path is checked for existence and a .real suffix is preferred.

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 uses the installed NVIDIA Container Runtime Hook wrapper
as the path in the applied config. This prevents conflicts with other
installations of the NVIDIA Container Toolkit.

This change adds an nvidia-container-runtime.runtimes config option.
If this is unset no changes are made to the config and the default values are used. This
allows this setting to be overridden in cases where this is required. One such example is
crio where crun is set as the default runtime.
