Shorten URL when uploading as archive with props

Is your feature request related to a problem? Please describe.
When uploading files as archive using a spec, with multiple groups having the same target, the archive in Artifactory will have the props of all of the relevant groups in the spec. It's done by concatenating all of the props to the URL, without omitting identical props (Artifactory does that for us). That might cause the UR be very long, and possibly pass the limit of the URL length.

Omit identical props.
