SGECluster in multiple queues

Hi,

I'm opening this issue here, because I'm not having much success with stack overflow (https://stackoverflow.com/questions/59391000/sgecluster-in-multiple-queues). Sorry for the noise.

I'm using `dask.distributed` to launch jobs on a SGE cluster (https://jobqueue.dask.org/en/latest/generated/dask_jobqueue.SGECluster.html#dask_jobqueue.SGECluster) via `dask.bags` and/or `dask.delayed`.

Everything works nicely. However, I may have some `dask.delayed` that should run in a specific queue on my SGE cluster (due to GPU availability for instance (or some other requirement)). How can I work this out on dask?

In other words, how can I define a dask_jobqueue.SGECluster with multiple queues and/or different resource specs? dask_jobqueue.SGECluster allows me to configure one cluster setup only (one queue, one resource spec, etc..).

Thanks
