test(customd2): add custom_d2/workload1 test configurations

First configuration is "small" - 3 DCs, 3 nodes per each.

Second configuration is "big" - 5DCs, 12 nodes per each.
This "big" setup never reached the "Test start" stage because of the
very slow bootstrap process in a multi-dc environment.
