This change udpates the ldcache locator to read the ldcache at construction
and use these contents to perform future lookups against. Each of the cache
entries are resolved and lookups return the resolved target.
Assuming a symlink chain: libcuda.so -> libcuda.so.1 -> libcuda.so.VERSION, this
means that libcuda.so.VERION will be returned for any of the following inputs:
libcuda.so, libcuda.so.1, libcudal.so.*.

This change adds a test for locating libcuda as a driver library.
This includes a failing test on a system where libcuda.so.1 is in
the ldcache, but not at one of the predefined library search paths.
A testdata folder with sample root filesystems is included to test
various combinations.

Since we use a map to keep track of the elements of a symlink chain
the construction of the final list of located elements is not stable.
This change constructs the output as this is being discovered and as
such maintains the original ordering.

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 ensures that the toolkit works with older
versions of the GPU Operator where runtime-specific envvars are
used to set options such as the config file location.

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.

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.

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.

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

This change aligns the creation of symlinks under CDI with
the implementation in libnvidia-container. If the driver libraries
are present, the following symlinks are created:
* {{ .LibRoot }}/libcuda.so -> libcuda.so.1
* {{ .LibRoot }}/libnvidia-opticalflow.so -> libnvidia-opticalflow.so.1
* {{ .LibRoot }}/libGLX_indirect.so.0 -> libGLX_nvidia.so.{{ .Version }}
