It's very easy to add glog.Info(config) calls for debugging (or actual
logging). In some scenarios those configs will carry sensitive tokens
and those tokens will end up in logs or response bodies.
Leaking of those stringified configs compromises the cluster.
Also implement fmt.GoStringer.

Ensure that bootstrap+clientcert-rotation in the Kubelet can:
1. happen in the background so that static pods aren't blocked by bootstrap
2. collapse down to a single call path for requesting a CSR
3. reorganize the code to allow future flexibility in retrieving bootstrap creds
Fetching the first certificate and later certificates when the kubelet
is using client rotation and bootstrapping should share the same code
path. We also want to start the Kubelet static pod loop before
bootstrapping completes. Finally, we want to take an incremental step
towards improving how the bootstrap credentials are loaded from disk
(potentially allowing for a CLI call to get credentials, or a remote
plugin that better integrates with cloud providers or KSMs).
Reorganize how the kubelet client config is determined. If rotation is
off, simplify the code path. If rotation is on, load the config
from disk, and then pass that into the cert manager. The cert manager
creates a client each time it tries to request a new cert.
Preserve existing behavior where:
1. bootstrap kubeconfig is used if the current kubeconfig is invalid/expired
2. we create the kubeconfig file based on the bootstrap kubeconfig, pointing to
the location that new client certs will be placed
3. the newest client cert is used once it has been loaded

certificate.FileStore only handles (cert, key) combined PEM files. This
PR allows (key, cert), which is what "openssl req -out foo.pem -keyout
foo.pem" generates.

With the current behavior, when kubelet starts, a `templateChanged`
event is always fired off because it only checks if `getLastRequest`
matches `getTemplate`. The last request only exists in memory and thus
is initially `nil` and can't ever match the current template during
startup.
This causes kubelet to request the signing of a new CSR every time it's
restarted. This commit changes the behavior so that `templateChanged` is
only fired off if the currently template doesn't match both the current
certificate and the last template.
