DNAC1.3.3.3

Description (partial)

Symptom:
- DNAC is not responding to VIP address after upgrade

- magctl appstack status | grep keepalived shows smaller service uptime than other services

- magctl service logs -r keepalived show the following exceptions:
ERROR | 8 | MainThread | Maglev-Keepalived | keepalived.py:386 | Could not start keepalived due to 'host_ip' |
Traceback (most recent call last):
File "/keepalived.py", line 375, in main
template_context = _build_template_context_v1(keepalived_vip_config)
File "/keepalived.py", line 138, in _build_template_context_v1
template_context["interface_map"] = _get_node_ip_interface_map(valid_nodes=nodes)
File "/keepalived.py", line 270, in _get_node_ip_interface_map
interface_address = iface_config["inet"]["host_ip"]
KeyError: 'host_ip'

- etcdctl get /maglev/config/node-<node ip>/network command returns similar output for one of the interfaces (host_ip key is not present):
{"interface": "eno2", "inet6_config": false, "inet6": {}, "inet": {}, "intra_cluster_link": false}
