split ede24 system test into separate modules

Because ede24 system tests require stopping/restarting server, there is
always the risk that the test ends (with a failure) with server in an
wrong and impredictible state. This would make the other tests to fail
in a strange way as well.

To avoid this problem, split the test into different modules, so if a
module fails, the other module is not impacted as it uses separate
server instances.
