Description of problem:
Since we move to the new UI, many elements have no proper selector like 'data-test-id' or 'data-test' or 'id'.

Why this is a problem to qe:
1. it's hard to locate the element while writing tests.
2. tests is more flaky.
3. tests is more fragile when UI changed.

examples about elements lack proper selector:
1. edit buttons on vm tabs: scheduling tab
2. `id="pf-select-toggle-id-2098"` is used for dropdown menu, which is not usable. such as disk source dropdown while creating the VM, add nic/disk modal.

Version-Release number of selected component (if applicable):
OCP 4.11
