ovirt-node of 3.3 introduces a complete new UI framework.

A new implementation of user interaction should be written, disconnecting the implementation from vdsm-reg.

UI DESIGN

oVirt Engine Registration

    Engine Host: _____________________
    Engine Port: _____443_____________
[x] Use SSL
[x] Engine is >= 3.2 (may be not required if we can detect this automatically)
[ ] Ignore current CA trust

    [OK]    [CANCEL]

Enable SSH user/password Access

[ ] Enable ssh password access.
    Password: ____________
    Repeat:   ____________

    [OK]    [CANCEL]

IMPLEMENTATION DETAILS

 * No fallback to http, protocol is explicitly selected.
 * If engine is >= 3.2 do not execute vdsm-reg but perform registration directly.
 * If ignore current CA trust download CA certificate and present fingerprint even if CA already exist.
 * Separate the tabs between engine registration and ssh access.

TECHNICAL DETAILS

 * Modular clean implementation.
 * Conventions similar to ovirt-host-deploy.
