Fix ordering of Images to OS

[toschneck]

What is the problem, where is it and why is it an issue?

UX is bad, you mostly should select first the OS and then the image, as the selection of the OS influence the image.

Suggest how to fix it, if possible

Move Selection of OS up, above Image section

[KhizerRehan]

AFAIK:

OSP is also directly influence with OS but just want to clarify the image is shared is for MD Dialog what about wizard?
Should Image should be moved above OSP in wizard?

Q1: Do we need target only Openstack Provider only?

There are other provider e.g

Clarification

• Kubevirt which shows System Image based on OS selection

Clarification:

• VSphere (VmTemplate) as the selection of the OS influence the image.

let me know if those providers needs to be changed also from UX perspective

Some Suggested Approach

Suggestion-1: Move Image up within OpenStack settings

• Just reorder fields inside the OpenStack panel: put Image at the top instead of middle.
• OS stays in the left column, Image stays in the right column they're closer vertically but still
  in separate columns.
• Smallest change, but only a partial fix.

Suggestion-2:

Move OS selection to the right column

• Take the OS toggle buttons (Ubuntu, Flatcar, RHEL, etc.) out of the left column and put them at
  the top of the right column, above the provider settings.

Suggestion-3: Is same then what you suggested but Specific
