Add reporter to report logs sent by foreman callback

When ansible fails to connect to remote host,
callback sends a report to Foreman without
any indication that the report comes from
Ansible. As a result, Foreman is unable
to determine the report origin.

This adds a 'reporter' attribute into
the logs that are sent.
