-- Disassociates a node from an AWS OpsWorks CM server, and removes the
-- node from the server\'s managed nodes. After a node is disassociated,
-- the node key pair is no longer valid for accessing the configuration
-- manager\'s API. For more information about how to associate a node, see
-- AssociateNode.
--
-- A node can can only be disassociated from a server that is in a
-- @HEALTHY@ state. Otherwise, an @InvalidStateException@ is thrown. A
-- @ResourceNotFoundException@ is thrown when the server does not exist. A
-- @ValidationException@ is raised when parameters of the request are not
-- valid.
