• User story:

User can pick the right compute machine size for her cluster.
As a user, I want a drop-down that easily lets me find the wanted instance size.  This drop-down shall allow me to search, mark versions that aren't supported by region selected and my account. I should be able to filter the dropdown by the family name (eg: m5 or m6 or c5 or t3) and the general grouping (eg: burstable, compute, memory, storage)

Acceptance criteria:

• For ROSA creation wizard
  • machine sizes that are generally available, but not available to my selected region are disabled/hidden.
  • machine sizes that are generally available and are available to my AWS account can be selected.
