Assuming this can still fail eventually (even after retries) we still
need a way in Heat to make sure we can delete the resource by looking it
up from the idempotency token.
Of course the idempotency token *should* be just the name, but since
most projects have inexplicably chosen not to enforce unique names (in
tenant scope), we're in the odd position of requiring 3 ways to look up
any resource (by name, UUID, and idempotency token). That's bonkers, but
what can you do?
