OIDC support

@kostobog @blcham (to discuss tomorrow) I moved the Navigation component within the OidcWrapper to have user context event logged in with Keyckloak

It might work now, if we set up the realm correctly, now I get:

ff-iauth-demo-fta-fmea-server  | [thread] ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [/fta-fmea] threw exception
