Tidy up some resume functionality

[delucchi-cmu]

Change Description

A few clean-ups that don't change much functionality of resuming catalog, margin cache, or SOAP generation pipelines.

• Moves delete_resume_log_files up to the super class, so all resume plans can use the argument.
• Exposes user options for retaining intermediate files in margin generation and SOAP, as this was requested for catalog import and might be useful here as well.
• Moves margin cache pixel calculation more into the planning stages. Reduces the scope of the variables, and the negative pixel calculation can count toward the "planning" phase time.
• Only create directories for margin cache if the leaf files will be created.
