// Func will cheack each in order, returing the first match found.
// By default, the system will assume that any custom plug-ins installed are
// preferred (in alphabetical order if more than one), then Azure, and finally
// Lucene as a last resort provider.
//
// It would be nice if there were a way to detect if a provider was configured
// and ready for use without fully instantiating the provider, but this may be
// cumbersome since interfaces can't specify static members, and any other
// mechanism seems like it would be somewhat convoluted for would-be plug-in
// autors to implement.
