Limit conn: use complex value in limit_conn_zone (ticket #121).
One intentional side effect of this change is that key is allowed only
in the first position. Previously, it was possible to specify the key
variable at any position, but that was never documented, and is contrary
to nginx configuration practice for positional parameters.
