Remove DatabaseDict and vectorize Datastore/Butler ingest APIs

      Description

      From #dm-middleware on slack:

      I'd like to get Datastores using the new schema stuff I added recently (TableSpec/FieldSpec) for anything they want to keep in the registry database, and I want to stop using a dict interface, as it's hard to map _setitem_ to insert and update, especially for bulk operations.  I'm thinking of:

      • Removing DatabaseDict and DatabaseDictRecordBase entirely.
      • Add abstract methods to StoredDatastoreItemInfo to translate to/from dictionaries that correspond to records to be saved.
      • Moving the logic for inserting and retrieving StoredDatastoreItemInfo from the database directly into GenericDatastoreBase.  That would probably be _insert_info and _fetch_info methods that replace _info_to_record and _record_to_info.
      • Overriding _insert_info and _fetch_info in InMemoryDatastore to save into a dict instead of letting GenericDatastoreBase's implementations write to the database.
