empty result

testcase dim-testsuite/t/todo/pool-add-subnet-ndr-1.t added.

I hope the output of ndcli show ip is parsed.

Seems this is a naming issue again, the flag/parameter names does not match what the API and rest of the documentation calls it;
from the man page:

  ndcli modify pool POOLNAME add subnet SUBNET [gw GW] [NAME:VALUE]...
          Add SUBNET to POOLNAME. If the subnet does not exist, it is created.
[...]
       --no-default-reserve
              don't reserve network and broadcast addresses
[...]

ndcli has --no-default-reserve,
DIM API has dont_reserve_network_broadcast.
So it currently "works as expected", I guess.

However, we should probably add a flag/parameter to not reserve .0s and .255s, while still reserving network and broadcast address.

     --no-reserve-class-c-boundaries reserve network and broadcast address but
                                     do not reserve addresses on class c (/24)
                                     boundaries

shall be implemented

     --no-default-reserve            don't reserve network and broadcast
                                     addresses, don’t reserve addresses on
                                     Class c (/24) boundaries

no-default-reserve is clarified to this behavior
