Title: Simpler interface for retrieving ColumnFamily instances (blocks statds integration)

Replace Map with Interface when retrieving `ColumnFamily` instances.

Try to envision a time when a metric may be stored in any of a number of different column families. This change will make it easier to amend how we look up CFs in the future.
