Detailed Description

We want to reuse the database backend connection and exchange code for other uses, in particular for hook libraries. But this code includes some calls to the system logger for debug and uncommon cases and of course we do not want to get log messages from a hook library to seem to come from DHCP server core.

The solution is to use a database logger which calls the right logger with mapped messages.
