This change adds a "required" option to the new toml config
that controls whether a default config is returned or not.
This is useful from the NVIDIA Container Runtime Hook, where
/run/driver/nvidia/etc/nvidia-container-runtime/config.toml
is checked before the standard path.
This fixes a bug where the default config was always applied
when this config was not used.

This change introduced a config.Toml type that is used as the base for
config file processing and manipulation. This ensures that configs --
including commented values -- can be handled consistently.

This change ensures that the Config structs from internal.Config
are used for the NVIDIA Container Runtime Hook config too.

If the config.toml has an empty root specified, this could be
passed to the NVIDIA Container CLI through the --root flag
which causes argument parsing to fail. This change only
adds the --root flag if the config option is specified
and is non-empty.

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 improves the error message when invoking the NVIDIA
Runtime Hook in non-legacy mode. This should guide users to specifying
the --runtime=nvidia flag when using docker.

This change renames the nvidia-container-toolkit executable
to nvidia-container-runtime-hook. Here nvidia-container-toolkit
is created as a symlink to nvidia-container-runtime-hook.
