add support for gw_priority, enable_ipv4 (requires docker v28.0)

This adds support for the GwPriority API field in API v1.48 (docker v28.0). It can be set on both docker container run and docker network connect. This option is used by the Engine to determine which network provides the default gateway for a container. It also adds support for enable_ipv4, which allows enabling (default) or disabling IPv4 address assignment for a network.
