SERVER-29225 Split off free functions in catalog.

The free (mongo namespace) functions in the catalog library are
all implemented in terms of the sliced public interface classes
for catalog functionality.  These can be made a separate library
which does not depend upon catalog but instead depends upon the
interface classes.
