Update ITEM_CREATE to V5
This PR updates the DOIT_SOA_ITEM_CREATE
API to V5. Please review this carefully, as there are a lot of new additions and I may have missed something (though I don't think I did).
This will not be included in the Techstore project until the DOIT_SOA_ITEM_UPDATE
API has also been updated, as they share parameters.
Tests will probably fail because the DOIT_SOA_ITEM_UPDATE_V4
schema doesn't appear to exist anymore (I would assume because @lloyd-carter is working on it).
