.travis.yml: only tag latest image if not git tag
If we tag a release for, e.g. 0.1.1, after we've already cut a 0.2.0
tag, then CI would tag the 0.1.1 image as `latest`, which is confusing.
This commit ensures that we only tag the `latest` image when building
from master.

pkg/iptables: remove nil rules from list on error
Previously, when `deleteFromIndex` exited early due to an error, nil
rules would be left in the controller's list of rules, which could
provoke a panic on the next reconciliation. This commit ensures that nil
rules are removed before an early exit.

pkg/mesh,pkg/wireguard: sync NAT endpoints
This commit changes how Kilo allows nodes and peers behind NAT to roam.
Rather that ignore changes to endpoints when comparing WireGuard
configurations, Kilo now incorporates changes to endpoints for peers
behind NAT into its configuration first and later compares the
configurations.
