update CNI to v1.0.0

[AkihiroSuda]

https://github.com/containernetworking/cni/blob/v1.0.0/Documentation/spec-upgrades.md

CNI v1.0 has the following changes:

• non-List configurations are removed
• the version field in the interfaces array was redundant and is removed

libcni Changes in CNI v1.0

/pkg/types/current no longer exists

This means that runtimes need to explicitly select a version they support.
This reduces code breakage when revendoring cni into other projects and
returns the decision on which CNI Spec versions a plugin supports to the
plugin's authors.

For example, your Go imports might look like

import (
   cniv1 "github.com/containernetworking/cni/pkg/types/100"
)

Full changes: containernetworking/cni@v0.8.0...v1.0.0
