[StarCluster] starcluster Failed to add new host but continues addings hosts when using loadbalance

[Ryan Golhar]

Hi all - I'm running starcluster loadbalance, and noticed when it runs into
a problem adding a node, it ignores the problem and continues adding nodes
which also fail...ie the node get started by never added to the SGE grid.
 Perhaps a check that all was successful would be in order prior to adding
more nodes:

/opt/sge6
