MCP MAXAR Deletes - Removing Verified Files

[krisstanton]

• Ensure this ticket is completed first: MCP MAXAR Deletes - Filter Inventory Lists and CMR Processing #409
• Create the python functions for reaching into DynamoDB and removing specific entries based on Granule Information from the list generated on the last ticket.
• Delete Verified Files from MCP using an S3 Batch Operation, a Custom Lambda and the list of granules that are safe to delete.
  • The Custom Lambda should delete S3 files AND remove Dynamo DB entries. If either of these two operations has an error, the current row should fail - So it can be run again.
• Keep a list of all files that were deleted (should be able to get this from the Batch Operation Success List)
  • Place this file somewhere accessible in an MCP S3 Bucket
  • Make a comment in here explaining where this file is located.
