Add the output of failed "systemctl status (service)" in the report

When running module tests on Jenkins a couple of times I've had to investigate the following failure:

Error: /Stage[main]/Ntp::Service/Service[ntp]: Failed to call refresh: Could not restart Service[ntp]: Execution of '/usr/bin/systemctl restart ntpd' returned 1: Job for ntpd.service failed. See "systemctl status ntpd.service" and "journalctl -xn" for details.

Instead of simply having "See systemctl status ntpd.service for details" it would benefit the customer, and the modules team, for the output of this command to be available in the report. Especially since it is often the case the testing environment no longer exists after tests have been ran. In the same way it would allow customers to access this without having to connect to their production system.
