This PR unpacks the downloaded ConfigMap to a set of files on the node. This enables other config files to ride alongside the KubeletConfiguration, and the KubeletConfiguration to refer to these cohabitants with relative paths. This PR also stops storing dynamic config metadata (e.g. current, last-known-good config records) in the same directory as config checkpoints. Instead, it splits the storage into `meta` and `checkpoints` dirs.
