[CE] Able to enforce IPv4 Only via REST API and CLI

7.0.2-6644 CE

Steps:

Install community edition on a single node cluster
Try to enable IPv4 only via REST:

[root@node1-cb700-beta-centos7 bin]# curl -X POST -u Administrator:password http://10.112.210.101:8091/node/controller/setupNetConfig -d afamily=ipv4 -d afamilyOnly=true

Retrieve /pools/nodes and we can see that it took effect:

[root@node1-cb700-beta-centos7 bin]# curl -u Administrator:password http://10.112.210.101:8091/pools/nodes

Attaching UI screenshot showing that it got enabled

CLI works as well since REST API is allowing it:

root@node1-cb700-beta-centos7 bin]# ./couchbase-cli ip-family -c localhost:8091 -u Administrator -p password --set --ipv4only
Switched IP family for node: http://127.0.0.1:8091
