DistributableSingleSignOn register an SessionIdChangeListener for each SSO session

      Description

      During performance testing on our app we noticed an continuous increase of CPU utilization while the load was constant.

      In turns out that for each session an undertow SessionListener was registered at login and was never unregistered (request.logout or session.invalidate).
      As a result all the operations on undertow SessionListeners are taking more CPU every time a listener is added as we loop over those listeners.

      First of all we should register only one (if needed) such SessionListener per webapp.

      But even in the current implementation, the listener was not unregistered when request.logout was called.
      It is unregistered when session.invalidate is called but then this is not the same listener that is provided and thus nothing is done.
