Recognition model and recognition date as fields per vendor

[sitescripter]

Case 1: Our recognition models are sure to change as we learn. We might want to update all images that were recognized by vendor AWS using model Generic before date 2018-08-30.

Case 2: When users notice an unsatisfactory recognition, we want to know the vendor, model, and recognition date that resulted in the metadata.

The field cf_aiMetadataModified allows us to find by date, but we don't know the model that was used. When using multiple vendors it becomes even more complicated, as Elvis doesn't give us access to the use of the nested data models of Elasticsearch. The cf_aiMetadataModified might not inform us about the recognition date from the vendor we're looking for.

Suggested solution: In lieu of access to nested data, the solution could be to have two fields per vendor:

1. Recognition model (cf_aiModelAWS, cf_aiModelClaro, ...)
2. Vendor specific recognition date (cf_aiUpdatedAWS, cf_aiUpdatedClaro,...)

Nice suggestion. Note though that we currently only support Clarifai when it comes to using different models. This could be something to further generalize though also for other vendors (See also #13).

Perhaps split it into two and focus on "Vendor specific recognition date"?
