ovn: add is_chassis_resident match expression component
This patch introduces a new match expression component
is_chassis_resident(). Unlike match expression comparisons,
is_chassis_resident is not pushed down to OpenFlow. It is a
conditional that is evaluated in the controller during expr_simplify(),
when it is replaced by a boolean expression. The is_chassis_resident
conditional evaluates to "true" when the specified string identifies a
port name that is resident on this controller chassis, i.e., the
corresponding southbound database Port_Binding has a chassis column
that matches this chassis. Otherwise it evaluates to "false".
This allows higher level features to specify flows that are only
installed on some chassis rather than on all chassis with the
corresponding datapath.
