Based on work done in hashicorp/memberlist#196 this allows to restrict the IP ranges that can join a given Serf cluster and be a member of the cluster. Restrictions on IPs can be done separatly using 2 new differents flags and config options to restrict IPs for LAN and WAN Serf.
This test does check that blocking IPs works on LAN

This allows restricting the IP ranges that can join a given Serf cluster and be a member of the cluster.
Restrictions on IPs can be done separately using 2 new differents flags and config options to restrict IPs for both LAN and WAN Serf.
This will allow to secure a bit more clusters as well as protecting non-encrypted clusters from an agent in dev mode to join clusters and thus fixing #5916
