Promote LocalStorageCapacityIsolation feature to beta

The LocalStorageCapacityIsolation feature added a new resource type ResourceEphemeralStorage "ephemeral-storage" so that this resource can be allocated, limited, and consumed as the same way as CPU/memory. All the features related to resource management (resource request/limit, quota, limitrange) are available for local ephemeral storage.

This local ephemeral storage represents the storage for root file system, which will be consumed by containers' writtable layer and logs. Some volumes such as emptyDir might also consume this storage.

Fixes issue #60160

This PR also fixes data race issues discovered after open the feature gate. Basically setNodeStatus function in kubelet could be called by multiple threads so the data needs lock protection. Put the fix with this PR for easy testing.

**Release note**:

```release-note
ACTION REQUIRED: LocalStorageCapacityIsolation feature is beta and enabled by default. 
```
