This change refactors the toml config file handlig for runtimes
such as containerd or crio. A toml.Loader is introduced that
encapsulates loading the required file.
This can be extended to allow other mechanisms for loading
loading the current config.

This change updates the logic to populate the options for the
nvidia runtime configs added to containerd or crio from a default runtime
if this is specified and a runc entry is not found.
This allows the default runtime values for settings such as SystemdCgroup
to be applied correctly.
