And infact through form based auth if sso is off (see the backend issue
METRON-1665). This PR just removes the need to process a spring login form in
the Angular app to lighten the load a bit and avoid having multiple front-end
login implementations to keep in sync (config and alerts have their own at
present). This is more about moving the same functionality out of the angular
layer and into a different page.
