LPS-43556 HttpService is using a wrong parameter when doing the include operation
LPS-43711 Register the servlet context within the pool even if the deployed module does not have a plugin context listener defined

If a WAB does not install PluginContextListener it does not get
registered in ServletContextPool. This prevents WebExtenderServlet to
properly dispatch requests to it.
LPS-43558 Avoid having a compile time dependency with HttpService to be able to retrieve the bundle context from an OSGi web plugin
