Podman creates the default bridge network with dns_enabled to false. Subsequent calls to podman network create then create bridge networks where dns_enabled is set to true causing containers on said network to make use of podman's dnsutil plugin. This results in latency issues for gateway connections. This change ensures that networks created use similar settings to that of the default bridge network which has no latency issues.
