MicroK8s 1.28.12 after node restart it doesn't join due to nf_conntrack

[grebennikov]

Microk8s 1.28.12 fresh deployment on stock 22.04 Cluster consists of 3 node, everything default. Shutting down node3, it turns to notReady. Bringing back up, waiting it to come back online. Minikube doesn't start correctly with

Error /proc/sys/net/netfilter/nf_conntrack_max not found

Need to load nf_contrack module manually, after that everything works as expected.
