disrupt_refuse_connection_with_* nemesises doesn't support ipv6.
When node is banned and alive, c-s/s-b could connect to it
and failed with critical error, because banned node return
that other node cluster is down.
This allow to block connections to scylla node from loaders
and avoid critical error of c-s/s-b if them connect to
banned node and failed to run
