We currently have updated information for most, if not all, owners of our performance tests. This bug is for integrating this information into our alerts so that the owner of the test gets CCed on the test failure.
For example, see here for talos owner information: https://searchfox.org/mozilla-central/source/testing/talos/perfdocs/config.yml#372
And here's an example of an alert: https://bugzilla.mozilla.org/show_bug.cgi?id=1773127
Which gets generated by a sheriff from here: https://github.com/mozilla/treeherder/blob/5bebdbfe74726efc96cf6968ac4e5a99ec627328/ui/perfherder/alerts/StatusDropdown.jsx#L170
We would need to make an owner field in perfdocs to make this simpler on the alert generation side (so we don't have to parse a string). Also, some tests are owned by groups so we would need to ask these groups to generate an email alias we can use to reach them with. That can be done in a separate bug though.
