Purpose
=======
Lighten the survey layout. it should be free of website footer and header.
Specifications
==============
Survey Layout inherits from web.frontend_layout, mainly to be able to use all
the styles rules defined in it and keep consistency between other frontend
pages and survey.
Instead of inheriting another layout, this PR sets no_footer and no_header to
True for all survey layout. The idea is to show only the survey itself without
having other web/website object in the layout.
