Major Description
The camel context must be provided, which currently is not a required option and therefore you can get null commands
Also we should flip the order of the arguments so you enter camel context first, so the completion of the routes are based on the given camel context.
Otherwise if you have 50+ camel apps in karaf, then the route complete will show all routes which is a lot. Now you select the camel app first, and then the completer only show the routes from this camel app.
