NETOBSERV-977: some interfaces on single stack cluster can have both ipv4 and ipv6 linklocal

[msherif1234]

We need to filter out interfaces with linklocal ips when we decide which socket type to use to connect to google dns server here is an example

2: enp0s20f0u5u2c2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
    link/ether fa:14:54:36:5a:55 brd ff:ff:ff:ff:ff:ff
    inet 169.254.3.1/24 brd 169.254.3.255 scope link dynamic noprefixroute enp0s20f0u5u2c2
       valid_lft 855315sec preferred_lft 855315sec
    inet6 fe80::2021:58f:8cf9:eca6/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
