not have to grope around in the cacher's data structures.

Whenever the manager gets a CLI command it does not understand, it
will pass it to the cacher process, if it is running.

This complicated "help" a little bit, because we want to show the
combined commands of the manager and cacher.

Since we're dealing with help anyway, hide undocumented debug
commands from it.
