nm: Use tabs for options/proposals to save screen space

The height of the dialog increased due to the recently added additional
fields for certificate selection and identities.  On some screens the
fields to configure custom proposals were not visible anymore.
Together with less spacing on the top level GtkBox this change reduces
the height by about 80 pixels.

Fixes #3448.
