b34402abd3 VRF CNI: Add an optional table parameter.
When specified from the user, the VRF will get assigned to the given
tableid instead of having the CNI to choose for a free one.

8d0d8a9547 Introduce a new VRF CNI meta plugin.
This plugin allows to create a VRF with the given name (or use the existing
one if any) in the target namespace, and to allocate the interface
to it.
VRFs make it possible to use multiple routing tables on the same namespace and
allows isolation among interfaces within the same namespace. On top of that, this
allow different interfaces to have overlapping CIDRs (or even addresses).

This is only useful in addition to other plugins.

The configuration is pretty simple and looks like:

{
    "type": "vrf",
    "vrfname": "blue"
}
