Yong Tang 249d4e5709 Show usage when `docker swarm update` has no flags ... This fix tries to address the issue raised in 24352. Previously, when `docker swarm update` has no flags, the output is ``` Swarm updated. ``` even though nothing was updated. This could be misleading for users. This fix tries to address the issue by adding a `PreRunE` function in the command so that in case no flag is provided (`cmd.Flags().NFlag() == 0`), the usage will be outputed instead. An integration has been added to cover the changes. This fix fixes 24352. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>		2016-12-13 05:05:04 -08:00
