unpack dynamic kubelet config payloads to files

Browse Source 
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.
