CNI: bump to 1.0.1 (#297)
* CNI: bump to 1.0.1

This commit bumps the declared version of CNI in the Kilo manifests to
1.0.1. This is possible with no changes to the configuration lists
because our simple configuration is not affected by any of the
deprecations, and there was effectively no change between 0.4.0 and
1.0.0, other than the declaration of a stable API. Similarly, this
commit also bumps the version of the CNI library and the plugins
package.

Bumping to CNI 1.0.0 will help ensure that Kilo stays compatible with
container runtimes in the future.
