SDC-970 - Update dataproduct filter mechanism

The dataproduct filter mechanism has been updated to be a bit smarter. It now uses Django's Q objects to do complexer queries.

• DataProductFilter model was updated with two extra properties:
  • inclusion_type: whether a filter should query as include (default) or exclude (basically a NOT... query)
  • cardinality_type: whether a filter should work on multiple values for the same field (e.g., AND x like a AND x like b ... )
• The user interface is modified slightly, the filter specification on the "Create/Update" screen now displays a <textarea> for filters with multiple values. Multiple values are separated by newline (anything fancier would make this story a lot more effort)
• Next to a migration for the extra columns, there is also a data migration that adds/modifies the correct filters for the requested changes
• Required fields on filters are changed: either a SAS id or project code is required (instead of always SAS ID)
