Imaging Pipeline Update

Here is what I am adding to/changing in the pipeline:

- Updated setup_logging.py with new log information
- Added psutil module to setup.py
- Changed num_cores value on cfg files
- Added number of cores to settings.yaml and template_settings.yaml files
- Created a script to check analysis performance in different environments
- Changed a few things in imaging_pipeline.py and run_imaging_pipeline.py
Once I found a file that ended in `drz.fits` that had the same length of a `c0m.fits` file. That's why I changed that.
