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 ensures that CLI tools that require the path to the
driver root accept both the NVIDIA_DRIVER_ROOT and DRIVER_ROOT
environment variables in addition to the --driver-root command
line argument.

Instead of relying only on Experimental mode, the docker daemon
config requires that CDI is an opt-in feature.

Since the `update-ldcache` hook uses the host's `ldconfig`, the default
cache and config files configured on the host will be used. If those
defaults differ from what nvidia-ctk expects it to be (/etc/ld.so.cache
and /etc/ld.so.conf, respectively), then the hook will fail. This change
makes the call to ldconfig explicit in which cache and config files are
being used.

Since the `createContainer` `runc` hook runs with the environment that
the container's config.json specifies, the path to `ldconfig` may not be
easily resolvable if the host environment differs enough from the
container (e.g. on a NixOS host where all binaries are under hashed
paths in /nix/store with an Ubuntu container whose PATH contains
FHS-style paths such as /bin and /usr/bin). This change allows for
specifying exactly where ldconfig comes from.

This change adds a --relative-to option to the nvidia-ctk transform root
command. This defaults to "host" maintaining the existing behaviour.
If --relative-to=container is specified, the root transform is applied to
container paths in the CDI specification instead of host paths.

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.

This change switches to using the reflect package to determine
the type of config options instead of inferring the type from the
Toml data structure.

In some cases we might get a permission error trying to chmod -
most likely this is due to something beyond our control
like whole `/dev` being mounted.
Do not fail container creation in this case.
Due to loosing control of the program after `exec()`-ing `chmod(1)` program
and therefore not being able to handle errors -
refactor to use `chmod(2)` syscall instead of `exec()` `chmod(1)` program.
Fixes: #143

This change skips the update of ld.cache in the container if it
doesn't exist. Instead, the -N flag is used to only create the
relevant symlinks.

This change refactors the use of the symlink filter to make it extendible.
A blocked filter can be set on the Tegra CSV discoverer to ensure that the correct
symlink libraries are filtered out. Here, globs can be used to select mulitple libraries,
and a **/ prefix on the globs indicates that the pattern that follows is only applied to
the filename of the symlink entry in the CSV file.
A --csv.ignore-pattern command line argument is added to the nvidia-ctk cdi generate
command that allows this to be set.

This change renames the csv.library-search-path option to
library-search-path so as to be more generally applicable in
future. Note that the option is still only applied in csv mode.

This chagne simplifies the nvidia-ctk config default command.
By default it now outputs the default config to STDOUT, and can
optionally output this to file.
