This extends the tap plugin API enabling the user to instruct the CNI
plugin the created tap device must be set as a port of an *existing*
linux bridge on the pod network namespace.
This is helpful for KubeVirt, allowing network connectivity to be
extended from the pod's interface into the Virtual Machine running
inside the pod.

This PR adds a plugin to create tap devices.
The plugin adds a tap device to the container.
The plugin has a workaround for a golang netlink library
which does not allow for tap devices with no owner/group
to be created. When no tap owner/group is requested, the
plugin will fall back to using the ip tool for creating
the tap device. A fix to the golang netlink lib is pending.
