This commit adds a function that prints (both long and short) options of a ovs-* command. To use this function, option '--option' is added to ovs-appctl/dpctl/ofctl and ovsdb-tool commands. A future patch will use the option output to conduct bash command-line completion. Signed-off-by: Alex Wang <alexw@nicira.com> Acked-by: Ben Pfaff <blp@nicira.com>
