wizard broken in non modal view

[Yves-Gwenael Bourhis]

When creating a network we get a wizard view since https://review.openstack.org/#/c/64644/
However even with JS activated, after a login timeout the view is in non modal mode.
This non modal mode is also accessible directly via the URL http://<You_Horizon_Server>/project/networks/create

First issue:
========
In this mode, the form doesn't show as a wizard anymore but with tabs as before, but the "next" and "back" buttons are not functional.

Second issue:
==========
The required fields raise their error only after clicking the "create button" (and not when changing tab) as they should in wizard mode. (can be tested thoroughly with https://review.openstack.org/#/c/63078/ )

    Make wizard workflow work when non-modal

    The JavaScript code that adds the wizard functionality was initialized
    only when the page was displayed as a modal. I moved the call to that
    initialization function into the template, so that it is called always
    when a wizard is displayed.
