Subject: [PATCH] feat: Allow to define Parent CSS Classes on Application
 Parent Container - MEED-7094 - Meeds-io/MIPs#144 (#916)

This change will allow to define a custom CSS class to a portlet using a
portlet.xml definition inside an init param with key 'layout-css-class'.
This CSS is part of portlet definition and not attached to a particular
of Portlet instance only.
