Add a trait func which should check the presence of CamelCatalog before execution

[squakez]

With #5378 we've added a check into all those traits that require the presence of a CamelCatalog in order to be executed. It would be nice to refactor that work and to transform that check into a generic trait func which can also be used by the documentation process and be able to automatically generate documentation. In this way we can let the user know which are the traits that cannot be executed when running a "sourceless" or a synthetic Integration.
