Add ability to filter concepts by Name Type & Description Type

[paynejd]

Example use case is populating a drop down of locales that have a ISO 639-2 code.

@snyaggarwal is this already supported? If yes, please close.

@snyaggarwal to add description to this ticket

[jamlung-ri]

Description Types: https://app.openconceptlab.org/#/orgs/OCL/sources/DescriptionTypes/

Tasks:

1. Will need to add name_types as ListField in ES (in ConceptDocument)
2. Add name_types in facets for Concept (in ConceptSearch)

@snyaggarwal from your comment, so I am planning to add name_types as name_types = fields.ListField(fields.KeywordField()) in ConceptDocument and a prepping for name_types as below

@staticmethod
    def prepare_name_types(instance):
        return list(
            instance.names.filter(type__isnull=False).distinct('type').values_list('type', flat=True)
        )

Is this okay. And if yes, I think I am to do the same for description types.

@PatrickCmd This looks good to me.

[jamlung-ri]

@PatrickCmd Maybe we can do a demo of this on our Dev call this week?

[snyaggarwal]

@paynejd @jamlung-ri I have tested this and merged in master.
Some example queries I tried:
/concepts/?description_types=Description
/concepts/?verbose=false&name_types=IETF+BCP+47,ISO+639-1+Non-preferred,Fully-Specified
Please give a final go-ahead to close this.

[snyaggarwal]

@paynejd @jamlung-ri This is now available in all environments. The concepts are reindexed (staging is still under indexing).

Looks good! @snyaggarwal Please let me know if I should document this anywhere e.g. ReadTheDocs.
