If the pluging receives portMappings in runtimeConfig, the pluing will add a NAT policy for each port mapping on the generated endpoints.
It enables HostPort usage on Windows with win-bridge.

DEL can be called multiple times, a plugin should return no error if
the device is already removed, and other errors should be returned. It
was the opposite for vlan plugin. This PR fixes it.

If the Linux kernel is not built with the parameter
CONFIG_BRIDGE_VLAN_FILTERING, passing vlanFiltering in
the Bridge struct returns an error creating the bridge interface.
This happens even when no parameter is set on Vlan in the CNI config.
This change fixes the case where no Vlan parameter is configured on
CNI config file so the flag doesn't need to be included in the struct.

Previously, if an IPAM plugin provided DNS settings in the result to the PTP
plugin, those settings were always lost because the PTP plugin would always
provide its own DNS settings in the result even if the PTP plugin was not
configured with any DNS settings.
This was especially problematic when trying to use, for example, the host-local
IPAM plugin's support for retrieving DNS settings from a resolv.conf file on
the host. Before this change, those DNS settings were always lost when using the
PTP plugin and couldn't be specified as part of PTP instead because PTP does not
support parsing a resolv.conf file.
This change checks to see if any fields were actually set in the PTP plugin's
DNS settings and only overrides any previous DNS results from an IPAM plugin in
the case that settings actually were provided to PTP. In the case where no
DNS settings are provided to PTP, the DNS results of the IPAM plugin (if any)
are used instead.

Adds a bool to the cni config that will add a policy that allows for loopbackDSR on an interface. Updates relevant documentation. Allows L2Tunnel networks to be used for L2Bridge plugin.
This PR add the option to configure an empty ipam for the macvlan cni plugin.
When using the macvlan cni plugin with an empty ipam the requeted pod will get the macvlan interface but without any ip address.
One of the use cases for this feature is for projects that runs a dhcp server inside the pod like KubeVirt.
In KubeVirt we need to let the vm running inside the pod to make the dhcp request so it will be able to make a release an renew request when needed.
We used to return error if no endpoint was found during delete. We now treat this as a success. If we fail during an add call, we now make a delete delegate call to the ipam to clean-up.
