Resolve "Add extra arguments to cta-change-storage-class tool to make sure the right file is being changed"

Resolve "Switch to json format when providing arguments from a file (cta-restore-deleted-files, cta-change-storage-class)"

Restoring deleted files implies restoring them in the eos namespace and
in the cta catalogue. The command has no atomicity guarantees, a file
may be restored in the eos namespace but the restoring in the cta
catalogue may fail.
