Can I set job weight in a pipeline script?

[William McLendon]

We're doing some experimentation in our environment with pipelines using the scripted interface.  Generally, it's doing what we want but we typically do jobs that use > 1 core and I haven't found any way to set the job weight in the pipeline script, so I thought I'd ask... is there any way to set the job weight in a pipeline script?  

Ideally, it'd be nice to set on a per node() {...} basis but I'm not terribly picky, being able to schedule N executors on our build slaves for the whole job would let us move forward.

Thanks!
