Subject: MINOR: log/backend: prevent "use-server" rules use with LOG mode
X-Git-Tag: v2.9-dev12~97

MINOR: log/backend: prevent "use-server" rules use with LOG mode

server_rules declared using "use-server" keyword within a proxy are not
supported inside a log backend (with "mode log" set), so we report a
warning to the user and reset the setting.
