Comment 7 for bug 1964881

I prepared a patch fixing this bug. Solved the issue by changing rsyslogd and logrotated's tomcat config using syslog:adm permissions.

This should be possible to apply to 22.04 and 21.10. Probably not to focal/20.04 as it is missing the patch which grants write access to `adm` group to `/var/log/tomcat9`

If combined with that, it can be applied to 20.04 also.
