[click_helper][ResourceOption] Allow exceptions when loading entry points

See merge request !122

So far the ResourceOption class tried to load a string as entry points
and would do this in a while loop. But sometimes an option may accept
both objects and some special strings like the dask client which can be
both "single-threaded", "threaded", and Client objects. Addition of
string_exceptions allows for this kind of special cases to be implemented.
