Fix Juju kubernetes-master idle status never being set

**What this PR does / why we need it**:

This fixes a problem with the kubernetes-master charm where the "Kubernetes master running." status message never gets set.

This happens because the `kube-api-endpoint.connected` state that it's waiting for doesn't exist. The state we need is `kube-api-endpoint.available` as seen [here](https://github.com/juju-solutions/interface-http/blob/master/provides.py#L12).

Additionally, we need to add the relation arguments to idle_status so it doesn't break when called.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #47676
