  2. Networking: Add support for multi-queue mactap 

    Provide multiple methods to connect the Virtual machine
to the container network. The current implementation allows
this to be chosen at a node level. In the future we can
enhance this to be dynamic, where the container interface
type is used to determine the optimal interconnection method.

Add support for multi-queue macvtap as an alternate means to
connect the container network interface to the virtual machine.

Include a workaround for kernel limitation around macvtap index
generation logic when interfaces are created within a namespace.

The switch from bridge+tap to macvtap brings in support for
  - multiqueue
  - lower latency
  - lower jitter
  - lower cpu consumption

Longer term this need to be configurable and the runtime should
be able to choose the networking model at a per pod level.
