request help: Health Checks can support customized PORT ?

[souzens]

sometimes http work and health check listen on different ports ,

like spring boot cloud
http api request works on 8080,
but actuator health works on 8888 port

so a router config like :

            "active": {
                "http_path": "/actuator/health",
                "port": "8888",
                "host": "test",
                "healthy": {
                    "interval": 2,
                    "successes": 1
                },
                "unhealthy": {
                    "interval": 1,
                    "http_failures": 2
                }
            },
            "passive": {
                "healthy": {
                    "http_statuses": [200],
                    "successes": 3
                },
                "unhealthy": {
                    "http_statuses": [503,404],
                    "http_failures": 3,
                    "tcp_failures": 3
                }
            }

i did not find any health port define in https://github.com/apache/incubator-apisix/blob/master/apisix/schema_def.lua#L81

is it supported now ?
