What is the policy about adding third-party components to the wiki?
Is it only for components in the main Camel repository? Are things that belong in Camel-extra welcome in the wiki? What about components that are not part of either repository, e.g. because of dependencies or just because the maintainer wants to keep the component in a personal Github repository? Even if the documentation for such components is not welcome on the wiki, is it OK to link to them on external sites from the component list page? This may also help to avoid conflict over URI prefixes in future.
