Introduce dual-stack Egress by enabling new fields spec.egressIPs and spec.externalIPPools. Both IPv4 and IPv6 egress IPs are always scheduled to the same Node via an extended consistent hash scheduler. The antrea-controller allocates IPs atomically from their respective ExternalIPPools in egress HA mode. The antrea-agent handles dual-stack Egress through a dedicated sync path that installs per-IP SNAT mark flows and iptables rules, and installs per-Pod OFPort flows for both IP families. Admission webhook validation ensures the dual-stack and single-stack fields are mutually exclusive. Signed-off-by: Shuyang Xin <shuyang.xin@broadcom.com>
