Fix dependencies to use slf4j instead of commons-logging
Fix dependencies to use slf4j instead of commons-logging

Adding commons-configuration pollutes our dependency tree
to automatically include commons-logging. Which will result in our
web console project to include log4j and commons-logging in the
same classpath.

As Kapua uses SLF4J this change does remove the dependency on
commons-logging from commons-configuration and adds jcl-over-slf4j
instead.
