"fetch" module is a good choice to pull the report back to a unique name. The
unique name will be automatically created by the module. Quoting:
"...default behavior of appending hostname/path/to/file to the
destination ... retrieving files that are uniquely named per host."
This behaviour can be switched off by "flat: true".
