Description / Background

Currently the Bulk Export Planner produces sparse logs. Therefore it is hard to know what is going on and difficult to debug.

Steps to reproduce

1. Deploy stacks 'BulkExportStack'
2. Send SQS message to start a bulk export
3. Check Cloud Watch Logs
4. See very little detail

Expected behaviour

More logs so that the user can see what is happening.

Technical Notes / Implementation Details

Add more info and debug logs.
