ynl: support binary and integer sub-type for indexed-array
Add binary and integer sub-type support for indexed-array to display bond
arp and ns targets. Here is what the result looks like:
# ip link add bond0 type bond mode 1 \
arp_ip_target 192.168.1.1,192.168.1.2 ns_ip6_target 2001::1,2001::2
# ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifname": "bond0"}' --output-json | jq '.linkinfo'
"arp-ip-target": [
"192.168.1.1",
"192.168.1.2"
],
[...]
"ns-ip6-target": [
"2001::1",
"2001::2"
],
