-- | Unassigns a registered instance from all of it's layers. The instance remains
-- in the stack as an unassigned instance and can be assigned to another layer,
-- as needed. You cannot use this action with instances that were created with
-- AWS OpsWorks.
--
-- Required Permissions: To use this action, an IAM user must have a Manage
-- permissions level for the stack or an attached policy that explicitly grants
-- permissions. For more information on user permissions, see <http://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html Managing UserPermissions>.
