Renamed the Apache module to WebAdmin module
More apache -> webadmin renames and moved Apache admin daemon to localhost:60080 so nginx can take over https port
Initial version having nginx as the reverse proxy for the webadmin UI (port 443). Nothing changes for other services
Merge branch 'master' into cperello/nginx-reverse-proxy
