// Deletes the specified role. Unlike the Amazon Web Services Management Console,
// when you delete a role programmatically, you must delete the items attached to
// the role manually, or the deletion fails. For more information, see [Deleting an IAM role]. Before
// attempting to delete a role, remove the following attached items:
//
//   - Inline policies ([DeleteRolePolicy] )
//
//   - Attached managed policies ([DetachRolePolicy] )
//
//   - Instance profile ([RemoveRoleFromInstanceProfile] )
//
//   - Optional – Delete instance profile after detaching from role for resource
//     clean up ([DeleteInstanceProfile] )
//
// Make sure that you do not have any Amazon EC2 instances running with the role
// you are about to delete. Deleting a role or instance profile that is associated
// with a running instance will break any applications running on the instance.
