NEXUS-6045: Swapping out restlet1x and stat-rsrcs

Caging Restlet under service/local and making
new static-resources plugin serve all non-REST resource
stuff from webapp.

Before, restlet1x was not only exposing REST services,
but also things like index.html, it's related redirects
WAR static resources and some other static resources.

After this, we move more away from restlet1x, truly
coexisting as equal citizen along siesta.

NEXUS-6045: Removing the intermediate "service" router

As restlet1x is now equal to what this router was before,
is mounted on /service/local
NEXUS-6045: Swapping out servlet order

Restlet1x is not anymore "last" as it's catch-all will not
interfere with others (like siesta) as is mounted under
/service/local and not ROOT anymore.

The static-resources plugin, that IS mounted on ROOT now
and serves kinda "catch all" trying to serve a static
resource if no other service handles the call.
