CA-393507: Default cluster_stack value

Add a `@default` attribute to the `cluster_stack` field in the cluster config. This field was introduced in #c1bd0e31a but causes RPU to fail since it is not optional, and while xapi-clusterd was unmarshalling an old db (which contains cluster config), it cannot find this field, and throws an exception. Adding `@default` can make the rpc library to fill this field in when it is missing, solving the above problem. Signed-off-by: Vincent Liu <[email protected]>
