Include SecondaryNetwork related configurations in the YAMLs to simplify usage with installation methods other than Helm, which also aligns with other features' configurations.

What does this sentence "veth interfaces bridged to the underlay network, with or without VLAN tagging" mean?

I checked the implementation of VLAN type and think the secondary network is a veth device connected to an OVS bridge with a pNIC attached, so isn't it essentially "Antrea can create secondary network interfaces using veth interfaces bridged to the underlay network"? "with or without VLAN tagging" means traffic from secondary network interfaces can support both VLAN tagging and non VLAN tagging.
