Add new module (tjuli-over-slf4j) to bridge tomcat juli log library over slf4j

Please consider adding this new module which is similar to jcl-over-slf4j but this is for the apache tomcat-juli project.

Tomcat-juli is a stripped down and repackaged version of commons-logging. Tomcat-juli by default uses JUL, but the jar can be drop-in replaced with a complete repackage of commons-logging.

This pull request encapsulates the code that reimplements the basic tomcat-juli so that the methods will invoke slf4j directly.

The main reason for this new module was not to be able to change Tomcat servlet container's logging but to be able to reconfigure the logging dependency of tomcat-jdbc which is a standalone jdbc connection pool library.
