In 1.8.4 hosts are getting assigned to an owner - how?

In 1.8.4 hosts are getting assigned to an owner - how? I want to change the
owner to the one that is our monitoring system. Even better would be to not
use any filtering in Foreman, and just send an e-mail (or SNMP Trap, or
Syslog) that we can point to our monitoring system (Zenoss) to handle event
alerting for us. We're already set up there for other monitoring and don't
really want to try and manage the e-mail alerting in Foreman also.

Maybe this is a feature request - dumb e-mail on puppet error to one e-mail
always. I don't assign owners in Foreman, at least not intentionally.

If I have to use this system, I need to be able to figure out how it picks
what the owner is during an automated sign of a SSL key / auto created
host. We're not pre-creating hosts in Foreman. We get them when Puppet
checks in for the first time.

Thanks for any clarity on this, and better still some work-around or way to
mass change who the owner is and set a default to be the e-mail address I
want to get notified.
