Today each storagenode should have a port which is opened for the internet, and handles DRPC protocol calls. When we do a HTTP call on the DRPC endpoint, it hangs until a timeout. This patch changes the behavior: the main DRPC port of the storagenodes can accept HTTP requests and can be used to monitor the status of the node: * if returns with HTTP 200 only if the storagnode is healthy (not suspended / disqualified + online score > 0.9) * it CAN include information about the current status (per satellite). It's opt-in, you should configure it so. In this way it becomes extremely easy to monitor storagenodes with external uptime services. Note: this patch exposes some information which was not easily available before (especially the node status, and used satellites). I think it should be acceptable: * Until having more community satellites, all storagenodes are connected to the main Storj satellites. * With community satellites, it's good thing to have more transparency (easy way to check who is connected to which satellites) The implementation is based on this line: ``` http.Serve(NewPrefixedListener([]byte("GET / HT"), publicMux.Route("GET / HT")), p.public.http) ``` This line answers to the TCP requests with `GET / HT...` (GET HTTP request to the route), but puts back the removed prefix.
