Changed the way report & test data output is configured and updated several configuration options for various ModeShape versions to workaround existing bugs: see MODE-2049 and MODE-2050.

This contains the changes from https://github.com/ModeShape/modeshape-performance/pull/12.

https://issues.jboss.org/browse/MODE-2049 and https://issues.jboss.org/browse/MODE-2050 means that the way the 3.4.x and 3.5.x repositories are configured is not "optimal" as monitoring needs to be turned on and client transactions must be used.

Also, after these 2 issues are fixed in master, the configuration for `modeshape-latest-tests` needs to be updated and checked.
