Today, it is not possible to use host-device CNI to move a
host device to container namespace if a device already exists
in that namespace.
e.g when a delegate plugin (such as multus) is used to provide
multiple networks to a container, CNI Add call will fail if
the targeted host device name already exists in container network
namespace.
to overcome this, we use a temporary name for the interface before
moving it in/out of container network namespace.
