Ian Campbell baabf6e8ad Ensure that plugins are only listed once in help outputs. ... They were listed twice in `docker --help` (but not `docker help`), since the stubs were added in both `tryRunPluginHelp` and the `setHelpFunc` closure. Calling `AddPluginStubCommands` earlier in `setHelpFunc` before the call to `tryRunPluginHelp` is sufficient. Also it is no longer necessary to add just valid plugins (`tryRunPluginHelp` handles invalid plugins correctly) so remove that logic (which was in any case broken for e.g. `docker --help`). Update the e2e test to check for duplicate entries and also to test `docker --help` which was previously missed. Signed-off-by: Ian Campbell <ijc@docker.com>		2019-01-30 13:55:42 +00:00
