Changes to error handling in alks_iamrole

• Previous behavior: Any error coming back from alks when attempting to read a remote role would be treated as a roleNotFound. This would lead to the terraform provider thinking a role was non-existent if there was a timeout or other error in the backend.
• New Behavior: Any error other then a 404 Role Not Found will result in erroring out of the plan or apply. Role not found will be treated as before, resulting in either erroring, or attempted re-creation depending on the attempted action.
