• 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, filter versions that aren't supported by region selected and my account.

Note: This story went through design changes after initial of testing. The final design conversation is captured here.

Acceptance criteria:

• For OSD cluster creation wizard (CCS) and for ROSA
  • machine compute types that are generally available, but not available to my selected region are initially hidden, but can be shown using filter switch.
  • machine compute types that are generally available and are available to my AWS account can be selected.
• For OSD Red Hat hosted (non CCS), and GCP

• • All machine compute types returned from /api/clusters_mgmt/v1/machine_types appear in the drop down. 
  • Filter switch ("Include types unavailable that might be unavailable to a region or account") does not appear in drop down.
