Log PurpleSharp test results to Attack Range

[ccl0utier]

It would be nice for PurpleSharp unit tests / playbook tests output to also be logged to index = attack like Atomic Red Team test results.

This could be achieved by adding the output file to the current list of monitored files in the Universal Forwarder inputs.
E.g., for ART: https://github.com/splunk/attack_range/blob/develop/packer/ansible/roles/windows_universal_forwarder/files/atomic_red_team_execution_inputs.conf

It seems PurpleSharp already logs execution output results (in JSON format) - but only for Playbook executions, not single tests. So @mvelazc0 would probably need to modify PurpleSharp accordingly first.

Once done we could update the Attack Range Reporting app to integrate PurpleSharp based results.
