Research re-architecting bulk data upload

[trycrmr]

A research task to get an idea of what it takes to re-architect the bulk data upload to have the following:

• Logging for debugging
• User notification on status (Refining what a "successful" upload means)
• Server-side validations
• Scale upload to n number of rows

Have this partially refactored on my local. Might revisit at some point.
