Translate no-vnc console types from CLI to API

Fixes #36

The terms "no-vnc" and "no-vnc-encrypted" are expected to be earily
unterstood by users, while the equivalent terms vnc-ws and vnc-wss
(respectively) are used in Compute API. Kamaki CLI will now
accept both terms by internally translating the former to the later.
