Provide scanner with image name and info

Issue projectatomic#1190 asks for an enhancement to atomic scan where
the scanner could figure out the image|container inspect
information prior to the scan.  We do this now by writing
a file in the scanout/ dir.  The file is JSON formatted
and could be ingested by a scanner that needed that type
of information.  The path should bexi
/scanout/inspect_info.json.
