core: handle s390 options more cleanly

Browse Source 
There are so many... so handle them as a table of key/value pairs
instead of having separate functions for each one.  At the moment
nothing but subchannels is used internally, but this allows plugins
to preserve options that NM doesn't care about when reading/writing
system configuration.
