Validate Transfer Manifest

[znatty22]

Validating the transfer manifest includes:

• Validate the content of the manifest according to the set of rules defined by the DFF team

  • e.g. certain file types have size restrictions

• (Accounting) Validate that the list of files in the manifest matches whats in S3

  • If files in S3 > files in manifest --> Error
  • If files in S3 < files in manifest --> Error
  • If files in S3 == files in manifest --> Success

• Write 2 top level functions to encapsulate the steps above. (Maybe) Expose each step in its own command

• Write a top level command that executes both validation steps. This will be called in the step of the step function
