use instance-name for syslog?

Hello,

When running multiple instances of dovecot on the same host (or running multiple docker container), it is hard to distinguish logs from different processes: the syslog entries are all prefixed with the same identifier "dovecot" It is hardcoded here: https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c#...

Would it make sense to use the already implemented instance-name as syslog ident? How do others solve that problem?
