Sync ignore checksum

[JPaja]

Option to ignore file checksum in case physical files gets removed while file cache still exists in database

[ColdHeat]

I think should probably be called sha1sum since we don't technically use the checksum string but otherwise I'm okay with this

[ColdHeat]

Just to make sure the intention for this is to force a reupload of the file to the server right?

[ColdHeat]

Okay I assume that this is for a situation where the file reference in the database is correct but the file itself needs to be reuploaded. I think this is okay but I imagine a better solution would be something like --force

[JPaja]

Yeah. I think issue i had was that I cleaned my s3 bucket but ctfd assumed that I still had the files uploaded.

@JPaja looks like I don't have permissions to edit your branch. Here's what I think this change should look like:

                        # Allow users to specify sha1sum in ignore to force reuploads
                        if "sha1sum" not in ignore:
                            if local_file_sha1sum == remote_file_sha1sum:
                                continue
