      * Previously, a deployment could not be scaled up or down when a `HorizontalPodAutoscaler` is present. With this update, when a deployment with an `HorizontalPodAutoscaler` is scaled down to `zero`, an *Enable Autoscale* button is displayed so you can enable pod autoscaling.

      Description of problem:

      Deployment cannot be scaled up/down when an HPA is associated with it.

      Version-Release number of selected component (if applicable):

      4.12

      How reproducible:

      100%

      Steps to Reproduce:

      1. Create a test deployment
$ oc new-app httpd
2. Create a HPA for the deployment
$ oc autoscale deployment/httpd --min 1 --max 10 --cpu-percent 10 
3. Scale down the deployment via script or manually to 0 replicas.
$ oc scale deployment/httpd --replicas=0
4. The HPA shows below status that it cannot scale up until the deployment is scaled up.
~~~
     - type: ScalingActive
      status: 'False'
      lastTransitionTime: '2023-10-24T10:00:01Z'
      reason: ScalingDisabled
      message: scaling is disabled since the replica count of the target is zero
~~~  
5. Since the scale up/down is disabled, the users will not be able to scale up the deployment from GUI. The only option is to do it from CLI.

      Actual results:

      The scale up/down arrows are disabled and users are unable to start the deployment.

      Expected results:

      The scale up/down arrows should be enabled or another option that can help to scale up the deployment.

      Additional info:
