Re: [DISCUSS] how about the design of APISIX eureka integration?

[~Jarvis.Qiu]

Eureka REST API:

https://github.com/Netflix/eureka/wiki/Eureka-REST-operations

we just need `GET /eureka/apps`, and its output:

{
    "applications": {
        "versions__delta": "1",
        "apps__hashcode": "UP_1_",
        "application": [
            {

                    }
                ]
            }
        ]
    }
}

tansform to the nodes of upstream:

{
  "192.168.1.100:8761" = 1,
}

others data (type, retries, timeout Etc.) of upstream are from configuration.
