This removes "Intro", which is actually no longer the recommended
get-started place (Learn takes that spot).
Additionally, there is now a separator between the high level business

This PR contains documentation additions for ingress and terminating gateways. New pages for the config-entries and overall feature description were added, as well as various additions to related pages.
