Description of problem:

When a customer adds nodes to a cluster outside of Hive MachinePools, MCE console will display a scaling alert saying that nodes are being scaled down, because it detects more nodes than there should be according to the MachinePool.

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

MCE 2.2, 2.3

How reproducible:

Always

Steps to Reproduce:

1. Add nodes to a Hive-deployed cluster by creating a new MachineSet on the cluster itself rather than a MachinePool on the hub cluster

Actual results:

Cluster overview page shows an alert claiming scaling down is in progress on the Nodes and Machine pools tabs.

Expected results:

No alert should appear.

Additional info:

Scaling alert can now be based fully on the MachinePool. Status includes readyReplicas that indicates when the machines are ready and have been added as nodes. See ACM-852 for changes in Hive that enable this.
