Add a FTSW page to restore a backup

Summary

We have to make it easy to restore a backup at first boot. A new page in First Time Setup Wizard (FTSW) should ask the user if he wants to recover a backup.

This new page should take place at the end and be shown in all cases.

If the user previously set is ecloud account, FTSW shows this page only if a backup is detected on the ecloud account.
