Base Process Patterns

[rleeson]

Description

As a developer, I need to import and manage site content changes from external sources in a repeatable, reliable manner, with a clear process to manage new, changed, and missing content, and potentially split across multiple batches for large, resource intensive content.

Approach and Changes

• Implement a set of base classes which add on to the previous with additional capabilities for the following Recurring import scenarios: Update, Destructive Update which prunes entities missing from the Import, and Batched Destructive Update which spans a large import of smaller batches
• New IBatchProcess and IDryRun interfaces to optionally add-on support Batched and Test/Dry Run Processes
• Add Stream and Process statistics models to help track, audit, and/or report the results of different processes
• Segment some Data and Process models into sub-namespaces for organization
