Add user-supplied arguments in log_handler

Sync from Oslo, change-id: I91289cc4a60f5dab89bca852e6f52b4b83831e47

When using PublishErrorsHandler, it will missing user-supplied
arguments. For example, do LOG.info("blabla %s", "foo"), the
payload only contains "blabla %s", but we expect it like "blabla foo".

Change firewall to DOWN when admin state down

Currently firewall remains in status "ACTIVE" after admin state
is changed to DOWN.

This fix sets firewall status to "DOWN" if admin state is updated
from "UP" to "DOWN". "DOWN" status is used by other network resources
so use "DOWN" to keep consistent.
