Supervisor should allow setting a tag for syslog logging #286
Description
Logs in syslog can have a tag, that is often used to identify process names. Supervisor logs contain the process name but this is not recognized as the process name, and is always supervisor.
While this works for simple cases, it becomes tiresome to filter different processes when managing many of them using supervisor.
For an example of how this should look, please see (in a debian/ubuntu system):
echo "test syslog message" | logger -t "test_app"
and then check /var/log/syslog
