Overwrite the default health check rule that modifies spring cloud

The MicroServices gateway is the socket long connection with the payment company docking, the gateway needs to provide the HTTP interface to the internal system call, when the socket is not established connection (Gateway service is high availability is haproxy, some services socket may not be connected to the payment company), so, At this point the HTTP service of the gateway does not let the internal other call system discover.

Overwrite the Dohealthcheck () method, increase the socket connection check to return the health check results to Consul, other microservices clients perceive which Gateway service is available.
