adds option for reduced stills_process logging

[dermen]

When running jobs in the terminal, this option suppresses a lot of refinement logging, and provides minimal progress feedback to user.

Awesome, this has been high on my list as well. Big carbon footprint reduction :)

I'll review soon, but I'm inclined to make this default, maybe with a couple adjustments to current logging calls to bubble up one or two key items.

@ndevenish I added handlers for xfel modules so that they could use the logging in dials. Is ok? See cctbx/cctbx_project#819. When that is merged, and with my new commits above, on this branch using @dermen's logging_option=disabled, dials.stills_process is utterly silent :)

File sizes for the logs from the 6 image SACLA h5 dataset used by test_stills_process:

• Main: 377K
• This branch, logging_option=suppressed (the new default): 75K
• This branch, logging_option=normal: 372K (the SauterPoon outlier printouts are now hidden unless sauter_poon.verbose=True
• This branch, logging_option=disabled: 0K

@ndevenish ok to merge? The xfel handler ok? Thanks and no hurry :)

[dermen]

Any status update here ?

Some folks are on leave but I think this is fine. Ima hit the auto-merge button. Thanks @dermen.
