option kube-proxy flag --conntrack-max-per-core

option kube-proxy flag --conntrack-max-per-core support in charm would be good to have, it is specially is needed for web facing apps which use a lot of DNS.

I've seen some cases elsewhere, where the conntrack table is filled from horizontally scaled DNS pods + a high volume of requests. This would be a welcome tunable option.
