[fofaraz]

• [x] ifconfig and findMyIp: we have option to set PUBLIC_IP in env but we need to update documents first
• [x] pubsub: already removed
• [x] /mine route: removed on pion
• [ ] undeploy: we still need this functionality, sometimes app party goes offline and resharing stops, we need to handle this scenario
• [x] onlyAdmin routes on gateways: onlyAdmin middleware is already removed and its routes can be enabled/disabled here: configs.routes.enable.crashReport
• [x] /analytics and crashReport, /insufficient route: /insufficient and /crash are sub routes of /analytics which are switch on/off from gteway.conf > crashReport
• [ ] cleanup or disable explorer: we still need explorer or at least "req-check" and "app"
• [x] dht‍ plugin: done
• [x] broadcast plugin: done
