Currently, Servers, Current Sessions and Services tables can be seen on the dashboard page.
filters and listeners should be there as well, so that we can have an overview of all available resources.
There should be also details page for filter and listener, from that page, parameters table and relationship table will be displayed in read mode only as filter and listener don't allow to be updated once created. Clicking the gear icon should allow to delete that filter or listener.
On current service details page, a listener relationship table should be shown with anchor link to listener details page.
