Code Issues Proposed changes

Remove warning about deprecated signer function 

Use of signer/verifier functions has been deprecated since
cryptography 2.0, and a deprecation warning is shown on
every use of the 'refstack-client sign' command.

Remove that warning by using the sign function instead
of the signer function, as described in:
