Zincati generates a lot of errors on FCOS

[evertmulder]

Describe the bug
On OKD FCOS nodes zincati generates a lot of errors.

journalctl -u zincati -f
...
systemd[1]: zincati.service: Scheduled restart job, restart counter is at 786.
systemd[1]: Stopped Zincati Update Agent.
systemd[1]: Started Zincati Update Agent.
zincati[200836]: [INFO ] starting update agent (zincati 0.0.11)

I do not know if the zincati service is used for OKD for OS updates or if this message indicate the OS is not receiving updates... Is there some documentation around this?

Version
Seen on:
4.4-beta5
4.5.0-0.okd-2020-06-16-144107

How reproducible
login to a node:

journalctl -u zincati -f

machine-os-content needs to have a few more labels so that Zincati could parse these

Zincati analyzes rpm-ostree commit, which we build using coreos-assembler dev-overlay. Unfortunately the latter can't set commit metadata.

The error is annoying, but harmless, so I'll move this out of Beta 6 milestone
