What happened + What you expected to happen

There are some flakes in e2e tests. After the creation of a ray cluster, there might be some inconsistencies between the RayService Object's nested RayCluster state and the RayCluster Object state, in details, the RayService.status.activeServiceStatus.rayClusterStatus.state is unset, but RayCluster.status.state is ready, and the application's status is ready as well.
While the the state field is replaced with Conditions, should we switch to Conditions in the e2e tests as well?

Reproduction script

This bug is a flakiness issue.

1. create a RayService in an e2e test;
2. query the values of ayService.status.activeServiceStatus.rayClusterStatus.state and RayCluster.status.state
