arv-put: error:
--update-collection cannot be used when reading from stdin.

I think this was done to avoid dealing with the interaction between the "put cache" and the fact that stdin isn't a file -- I don't think there's any reason it can't work, we just chose to avoid the corner case by disallowing it.
A customer tried to do this and was confused that it didn't work. The use case is facilitating transfer from another storage system to Keep by piping to arv-put, where multiple files need to be placed into the collection. We should support it.
