=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)
