Assess the existing Clarifai tags

[AetherUnbound]

Description

Once the filtering is in place (#4646, though not necessarily blocked by it), we can construct an exhaustive set of Clarifai labels and determine exclusions for that provider using the approach described in the IP. Then the Clarifai label exclusions can be added to #4541 in the same way Rekognition’s are added and the blanket exclusion for all tags from that provider can be lifted. These exclusion lists could be combined into a single filtering step, or we could have individual filter lists based on the label provider. My preference is former, since that way the single list serves as a more exhaustive exclusion list.
