vsh: Introduce '--completers-missing' for 'self-test' command

Browse Source 
Make it simple to spot which options of which commands are missing
autocompletion functions by introducing this hidden option.

In the future when we'll have completers for everything this can be also
used as a hard fail so that completers are always added.
