Describe the feature request

We currently use a hard-coded formula for determining how many processes to use in DISP-S1 SCIFLO processing. We should make this formula a bit more flexible by getting some of the parameters from settings.yaml so that change to this formula doesn't require a new PCM release and deployment. It's currently here:
https://github.com/nasa/opera-sds-pcm/blob/develop/opera_chimera/precondition_functions.py#L385
n_parallel_bursts = max(int(round(available_cores / 2)) + 1, 1)

Make the following changes to that function:

1. Parameterize the division factor and the constant factor so that they are retrieved from settings.yaml. Have reasonable values if they are not found.
2. Make the default value of the denominator be 4 instead of 2. The constant factor can still be 1.
3. I'd also make change that formula so that it's a multiplication instead of division. This allows for maximum flexibility and the most straightforward. So the currently formula would look: n_parallel_bursts = max(int(round(available_cores * 0.5 )) + 1, 1)
4. At this point might as well parameterize theads_per_worker too
   https://github.com/nasa/opera-sds-pcm/blob/develop/opera_chimera/precondition_functions.py#L380
   threads_per_worker = available_cores
