Submit multiple UUIDs in UpdateProofController

[phptek]

At the moment, the UpdateProofController will only submit individual UUID's (node_hash_id JSON field) to the proofs REST endpoint. This endpoint is however capable of having multiple (up to 1000) submitted simultaneously.

In order to reduce the no. network requests the application needs to make to the Chainpoint network, the CLI controller should be able to produce full-proof requests for each version of each applicable class, all at the same time.
