      Description

      The butler.get(dataset + "_md", dataId) pattern is only supported for images, not catalogs. It would be useful to allow this to work on catalogs.
      At the same time, it would be useful to add support for getting the length and schema of a catalog.

            John Parejko, would you mind reviewing this, please? There's some cleanup as well as adding the new functionality. It's currently going through Jenkins.

                CameraMapper: simplify setting of extra dataset features
                
                Extra dataset features (e.g., "raw_sub", "raw_md", "raw_filename") are
                are created from the original mapping (e.g., "raw") by defining a bunch
                of extra methods. This patch replaces the sea of
                    if not hasattr(self, someName):
                        setattr(self, someName, someImpl)
                calls with a common function to set the implementations for each extra
                dataset feature. This clarifies the code and makes it easier to add more
                extra features.

                CameraMapper: add extra dataset features for catalogs
                
                Added "foo_md", "foo_len" and "foo_schema" if "foo" is a catalog.
                
                Note that the "foo_schema" commonly has a different meaning because it's
                usually defined explicitly if the "foo" is an important pipeline output.

            Sorry, that Jenkins was for another issue (not even mine).

            The relevant Jenkins is this one.
