/ext/health endpoint missing

[Sanghren]

Hello,

I noticed that /ext/health endpoint is missing in Slopes .

I'm using it for my small dashboard project and I would like to migrate all my calls via Slopes :)

Should I start a PR on this or was it left out intentionally ?

By the way this endpoint is not documented, I'll open an issue over there as well :)

Edit : Add an example of call / response :

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"health.getLiveness"
}' -H 'content-type:application/json; http://localhost:9650/ext/health' 

{
  "jsonrpc": "2.0",
  "result": {
    "checks": {
      "network.validators.heartbeat": {
        "message": {
          "heartbeat": 1590918823
        },
        "timestamp": "2020-05-31T09:54:36.733208646Z",
        "duration": 7434,
        "contiguousFailures": 0,
        "timeOfFirstFailure": null
      }
    },
    "healthy": true
  },
  "id": 1
}
