Service Offering with a fixed root disk size

SUMMARY

The UI shows a toggle to customize the root disk size upon deployment even though if the root disk size has been set to a fixed value under the service offering.

This toggle should be hidden when a offering is selected which does not allow for customization of the root disk size.

Above is the output of the API and below a screenshot of the UI.

This offering has a fixed size of 30GB.

We probably want an if-statement like (pseudo):

allowRootDiskResize = True

if rootdisksize > 0:
  allowRootDiskResize = False
