Cluster readiness reports Healthy when still not joined

[danielmoriya]

I'm adding the latest Akka.HealthCheck.Cluster package. Although the Readme says that it will return unhealthy when Actor system, is up, but still not joined the cluster, the results I'm getting a Healthy status with just the message for both liveness and readiness, that still not joined.

        "akka-live-cluster": {
            "data": {
                "message": "not yet joined cluster"
            },
            "description": "Akka.NET cluster is alive",
            "duration": "00:00:00.0000842",
            "status": "Healthy",
            "tags": [
                "akka",
                "live",
                "cluster"
            ]
        },
        "akka-ready-cluster": {
            "data": {
                "message": "not yet joined cluster"
            },
            "description": "Akka.NET cluster is ready",
            "duration": "00:00:00.0000657",
            "status": "Healthy",
            "tags": [
                "akka",
                "ready",
                "cluster"
            ]
        }

We relaxed the cluster healthcheck rules here: https://github.com/petabridge/akkadotnet-healthcheck/pull/238 Basically, the readiness probe only returns unhealthy if all other nodes in the cluster is unreachable
