Bin Xu 53d3b1bced 1, use 'disjointdhcps' for nodeset disjoint mode
2, handle 'disjoint' in preprocess method, to make sure that no request will be sent to SN which does not manage the nodes.
3, refine 'stat' to make sure it could query unmanaged nodes on-demand.

=head3 getNodesetStates
returns the nodeset state for the given nodes. The possible nodeset
states are: netboot, install, boot and discover.
Arguments:
nodes --- a pointer to an array of nodes
states -- a pointer to a hash table. This hash will be filled by this
function.The key is the nodeset status and the value is a pointer
to an array of nodes.
Returns:
(return code, error message)
