[saga-rg] JobService.submitJob() query

I would go for the resource manager as the thing being specified. The 
notion of specifying a host seems strange with large clusters & resource 
brokers. If the underlying middleware exposes each underlying host as an 
execution target... then effectively each host has its own 'resource 
manager' capability.

On its own I'd consider this an invalid argument. If there are 
additional attributes being provided to qualify resource selection... 
maybe OK. But the "" I would see as input to a resource broker which 
would select a resource manager as the execution target. Not a 
capability embedded into the current SAGA layer. My 2p.
