Set field length/values as actual attributes.

The SimpleMetadata class in metadata.py tries to getattr() attributes
on a field. For this to work, max_length and min_length have to be
actually set as an attribute.
Did the same for min_value and max_value and added those two to
SimpleMetadata.get_field_info
