Support a delete only option (disables transfer)

[PascalSl]

Feature Request Description

When using synccopy, there is the ability to delete extraneous files, but this only works in conjunction with syncing the files. There is no option to say that syncing is not necessary, but deletion is.

The usecase is this: we have an azure storage container which we use as our source. However, there are some files on the source that are deliberately not pushed to the destinations. We don't want the additional files to appear on the sources.
Then again, when a file is not on the source, we are sure we don't want it on the destination. That's why we are looking for a flag that disables syncing, while allowing deletion.

Can you keep us up to date whether this can be put on the Blobxfer roadmap somewhere or if any additional information is required?

Describe Preferred Solution

Be able to set a configuration parameter (ie. CLI: --disable-syncand, YAML: disable_sync ), that disables the syncing.

Describe Alternatives Considered

AzCopy, which doesn't do Azure to Azure comparison

This option should apply to all transfer modes.

This has been added in develop. The option is --delete-only (or delete_only: true). Please provide feedback if possible.

Thanks for the swift response. Can't say when I'll be able to do the check, in the meanwhile I've been assigned different tasks, but it's somewhere in my todo.
