Drain type handler

This is an interface between slog-config and handler of particular type of the drain that can be described in the config.

slog-config builds a Drain by quering each element of list of DrainFactory-ies.

By implementing this type external code can be used to extend possible interpret a piece of config and produce each piece of a resulting Drain.
