Hide option to scale replica set when it's not possible

[jansav]

Describe the bug ~It just doesn't do anything. No indication that something is happening, or that something went wrong.~

Scaling shouldn't work here, because it's controlled by Deployment. Option to scale should be hidden when it's not possible.
