On a busy Jenkins controller, the service logs can have thousands of lines like this generated in a day:

2020-10-22 12:57:45.509+0000 [id=291063]	INFO	h.p.jira.JiraChangeLogAnnotator#annotate: Annotating Jira id: 'OPS-22386

This pollutes the logs and makes it hard to debug other problems. These logs should be using a lower level to reduce noise, as they are of limited value under normal circumstances.
