RolloutPhaseHealthy indicates a rollout is healthy.

RolloutPhasePaused indicates a rollout is not yet healthy and will not make progress until unpaused.

RolloutPhaseProgressing indicates a rollout is not yet healthy but still making progress towards a healthy state.

RolloutProgressing Rollout 处于中间状态，一般是新RS被创建，新pod正在扩容中，或老pod正在缩容中。.

RolloutReplicaFailure ReplicaFailure is added in a deployment when one of its pods fails to be created or deleted.
