Currently --ami does not check instance types, creates invalid io_properties.yaml on unsupported instance types. It actually won't occur on AMI startup, since scylla_ami_setup only invoke scylla_io_setup --ami when the instance is supported, so we don't get the issue on startup, but we still get when we run scylla_io_setup manually. It's better to check instance type on scylla_io_setup, too. Refs #5438
