as a user, I would like to know the approximate size of a yum repo export before exporting
Currently, there is no way for a user to know how much disk space a yum repo export will take before the export occurs.
Pulp provides enough information to get a ballpark estimate on this, via RPM file sizes. We could add 10MB as a conservative guess on repo metadata, and return that.
This would likely need to be implemented in two places: an additional option to repo export, and also to and CV version export
