systemd issues on RHEL7

[joshuabaird]

Even after the recent 2.8.2 release, I'm still having issues on RHEL7. systemd doesn't think the webhook is running when it actually is:

root@pupqa-d1-pm01:~# ps aux | grep webhook
root     31153  0.0  0.0 112640   960 pts/2    S+   14:18   0:00 grep --color=auto webhook

root@pupqa-d1-pm01:~# systemctl status webhook
