fix typos

Previous behavior:
$ kubectl get hosts
F1119 11:47:44.787154   29017 resource.go:111] no resource "hosts" has been defined

fix kubectl log completion

Fix etcd unpack by adding a explicit x flag.

When kubectl started returning the right object it changed the template
that needed to be used to get the name of the containers inside the pod.

Ensure that kubectl get works with downstream resources

This fully encapsulates decisions about conversion within GetPrinter,
which prevents users from accidentally not converting.

Implements a credentialprovider library for use by DockerPuller.

This change refactors the way Kubelet's DockerPuller handles the docker config credentials to utilize a new credentialprovider library.

The credentialprovider library is based on several of the files from the Kubelet's dockertools directory, but supports a new pluggable model for retrieving a .dockercfg-compatible JSON blob with credentials.

With this change, the Kubelet will lazily ask for the docker config from a set of DockerConfigProvider extensions each time it needs a credential.

This change provides common implementations of DockerConfigProvider for:
 - "Default": load .dockercfg from disk
 - "Caching": wraps another provider in a cache that expires after a pre-specified lifetime.

GCP-only:
 - "google-dockercfg": reads a .dockercfg from a GCE instance's metadata
 - "google-dockercfg-url": reads a .dockercfg from a URL specified in a GCE instance's metadata.
 - "google-container-registry": reads an access token from GCE metadata into a password field.
