Remove log4j config files from etc.
Move apacheds server dependencies to allow other unit tests to run.
Temporary commit for files that need further work.

There are various log4j features in use here that need to be replaced by their
slf4j/logback equivalents. In this commit have had logging configuration specific
to log4j commented out so that they build.

The importer-specific files will be overhauled in the per-fileset logging work. Any
remaining files will be fixed once the current branch is tested and merged in.
Modify two blitz tests to use logback directly.
