The cluster.wait_ready() command fails when the RayCluster doesn't have status

[roytman]

Describe the Bug

The cluster.wait_ready() checks the status of the AppWrapper and, after that the RayCluster.
Which is done with sub-commands _map_to_app_wrapper and _map_to_ray_cluster.
Both of them check fields of Status, which cannot be defined.
The PR #254 fixed the AppWrapper check, but it did not fix the RayCluster check.
