slurm time flag in the hpc config is not being picked up.

When running vsim.py, the time flag in the hpc config is not being picked up (but providing override works).

This is by design -- the time required really depends on what's running, so specifying it in the global hpc config doesn't really make sense. I set it up to estimate it (for bridges GPU currently) automatically from the input parameters, and add that as a slurm override (unless it already exists as an override). But we could make that function estimate better....
