Subject: [PATCH] SCRD-2694 Synchronize the index with current venvs

With the SUSEification effort we deploy the venvs inside an RPM
package, so when a new version of the venv is installed the old
one get removed from the `ardana_packager` directory.

As of today there is not co-installation for multiple versions
of the same venv service.

This patch makes sure that when an old venv tarball is removed,
it is also removed from the venv index.
