Description of issue:
In a ready ROSA cluster under machine pools tab , user has invoked Actions menu > Edit machine pools option. User has changed one of the machine pool definition ex, node count and saved the changes. Edit machine pool dialog has closed but the changes were not reflected in the machine pool tab. It required a manual refresh or auto refresh run on the cluster page. This is wrong and we should get updated with machine pool table definition right after user click save action from Edit machine pools dialog.

How reproducible:

 Always

Steps to reproduce:

1. Launch OCM Staging.
2. Open a ready ROSA cluster and navigate to machine pools tab.
3. Click on "Action" menu and click "Edit machine pools".
4. In Edit machine pools, Change the node count value for selected machine pool.
5. Click "Save" button.
6. See the machine pool definition on machine pool table.

Actual results:

The machine pool definition in machine pool table stay as previous once user change the definition and saves from the "Edit machine pools" dialog. To reflect the machine pool definition, it required a manual or wait for auto refresh to run on the cluster. 

Expected results:
The machine pool definition in machine pool table should be updated once user change the definition and saves from the "Edit machine pools" dialog.
