Support connections between portals

[thejhh]

• Initial example configurations
• Configuration type definitions
• Connect a portal service to another portal service
  • through a socket file
  • through a custom system command (eg. over SSH), see Support to create a HTTP connection through a custom piped command (eg. SSH command) #19
  • through a HTTP address
  • through a HTTPS address, see PTTH connection support using HTTPS #20
  • If a connection fails, it must reconnect after a timeout (eg. 5 seconds).
• Listening portal connections
  • through a socket file
  • through a HTTP port
  • through a HTTPS port (Listening for a connection on HTTPS port #11)
• Route a connection to the service through a remote portal
  • Authentication of the request must be checked on both systems, if "auth" property is defined on the route, based on each portal's auth configuration, see HTTP password / username support #17
• Support for mapping to a different path than the main path
