We have enabled the command line options without changing a single line of code, we only had to replace old include with scylla_test_case.hh. Next step is to add x-log-compaction-groups options, which will determine the number of compaction groups to be used by all instantiations of replica::table. Signed-off-by: Raphael S. Carvalho <raphaelsc@scylladb.com>
