pre-upgrade job to verify function references and restricted privileges for fetcher and builder SA (#717)

It is mandatory (from this release onwards) for function to refer to secrets, config-maps and packages in its own namespace to ensure isolation of users sharing the same cluster. This change runs a pre-upgrade job to verify function references for all functions created prior to this release and fails the upgrade by printing a list of functions that violate this restriction.
