[carolinaecalderon]

Ticket

CM-528

Description

Change log level of log retention policy logs to "Info" level, not "trace".

INFO[2024-09-16T10:36:29-06:00] deleting expired task logs                    component=log-retention default-retention-days=-1
INFO[2024-09-16T10:36:29-06:00] deleted expired task logs                     component=log-retention err="<nil>" rows=123

Test Plan

N/A.
Spin up on your own test cluster to verify, set master config values for log retention policy/days. Then, clean up with det task cleanup-logs. You should see these log levels in the Info level.
