* 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.
