Check if k8s resources are supported in `runReflectorUntil`
Check if k8s resources are supported in `runReflectorUntil`

`isResourceSupported` checks whether a kubernetes resource is supported by the api server.
This ensures that, if the probe is unable to communicate with the api server, the call is retried until a true/false response.

If `isResourceSupported` returns false, `ListAndWatch` is not called and `runReflectorUntil` just exits.
