Title: Remove deprecated class AdminServletContextListener.

Remove servlet context listener that has been deprecated for a while. This is a breaking change, so it will probably have to wait until 4.0.0.

As noted in removed file, MetricsServlet.ContextListener and HealthCheckServlet.ContextListener
should be used instead.
