Yu-Ju Hong 4a72addaeb Factor out API defaulting from validation logic 
Currently, the validation logic validates fields in an object and supply default
values wherever applies. This change factors out defaulting to a set of
defaulting callback functions for decoding (see #1502 for more discussion).

 * This change is based on pull request 2587.

 * Most defaulting has been migrated to defaults.go where the defaulting
   functions are added.

 * validation_test.go and converter_test.go have been adapted to not testing the
   default values.

 * Fixed all tests with that create invalid objects with the absence of
   defaulting logic.

Joe Beda 76df5471b5 Covert the kubelet binary to hyperkube. 
This leaves `pkg/kubelet/server/server.go` looking a little ugly as there is an extra layer of "config" structs that isn't needed.  This is left as a TODO for now.

Matt Moore 2d396797a9 Fix for issue 3797. 
Docker's logic for resolving credentials from .dockercfg accepts two kinds of matches:
1. an exact match between the dockercfg entry and the image prefix
2. a hostname match between the dockercfg entry and the image prefix

This change implements the latter, which permits the docker client to take .dockercfg entries of the form:
   https://quay.io/v1/
and use them for images of the form:
   quay.io/foo/bar
even though they are not a prefix-match.

Filipe Brandenburger 79ff06ffa1 Fix comparison of EtcdClient to nil so that it does not run into the pointer vs. interface issue 
This is a partial rollback of commit 6e6f465a36 ("Fix a crash for
kubelet when without EtcdClient") in which we used the `reflect` module
to inspect that the pointer stored inside the interface was `nil`, but
as pointed out by @lavalamp, the correct solution is to make the
function return the interface type, in which case a `return nil` will
return the interface nil and not a nil pointer that turns into a non-nil
value when coerced into an interface.

For more details, see http://golang.org/doc/faq#nil_error and the
discussion in PR #3356.

Tested by installing a kubelet built from head with this patch into a
containervm instance and confirming it did not crash on standalone.go.
Confirmed that by only removing the `reflect.IsNil()` comparison but not
changing the return type of `EtcdClientOrDie()` did indeed cause that
same crash, so changing the return type does indeed fix the issue.

Eric Tune b759f67ee3 Kublet watches Pods. 
Added a kubelet config source for watching pods on apiserver.
The pods are converted to boundpods for merging with other
config sources.

The preferred way to create a kubelet is now to pass an apiserver
client but not an etcd client.  Changed cmd/integration to use
apiserver to talk to kubelets.  And cmd/kubernetes.

Unit, integration, and e2e tests pass, except for a failure of the pd
e2e test which was unrelated.

call APIs that do not run through SyncPods.  We really ought to be enforcing
invariants better.

Angus Lees 6f14e2e210 Avoid race between image pull and garbage collect 
Hold the pullLock while pulling regular container images, not just the
network container.

Also: previously, the locks were grabbed at too-low a layer in the
callstack, leaving a (narrow) window where images could be pulled and
then garbage collected before being used.

This change takes the existing pullLock a layer higher in the call stack
so the critical regions encompass the entire find+delete and pull+use
operation in both cases.

Tim Hockin 652479a3b1 Add kubelet DNS flags & api disable for DNS 
This adds --cluster_dns and --cluster_domain flags to kubelet.  If
non-empty, kubelet will set docker --dns and --dns-search flags based on
these.  It uses the cluster DNS and appends the hosts's DNS servers.
Likewise for DNS search domains.

This also adds API support to bypass cluster DNS entirely, needed to
bootstrap DNS.

Federico Simoncelli 4af64b8911 api: add container's id to ContainerStatus 
Sometimes for external applications it is useful to correlate the pod
containers to the real docker instances.

This patch adds a new entry in the container status (containerID) which
is used to identify the instance.

Eric Tune f122fc94bf Move service enviroment vars code. 
GetServiceEnvironmentVariables (originally in  pkg/registry/service/rest.go)
is split into two parts: one that lists services, and one that turns
a ServiceList into environment vars.  This will allow a subsequent PR
to add a call to the latter function with an existing ServiceList.
The former part is moved into pkg/registry/pod/bound_pod_factory.go.
The latter part is put in a new package, pkg/kubelet/envvars/envvars.go.
The new package is under kubelet because the container enviroment is more
associated with kubelet than with registry.
Test code moved too.

Matt Moore 0c5d9ed0d2 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.

Clayton Coleman 892942af8f Read BoundPods from etcd instead of ContainerManifestList 
There are three values that uniquely identify a pod on a host -
the configuration source (etcd, file, http), the pod name, and the
pod namespace. This change ensures that configuration properly
makes those names unique by changing podFullName to contain both
name (currently ID in v1beta1, Name in v1beta3) and namespace.

The Kubelet does not properly handle information requests for
pods not in the default namespace at this time.

Dawn Chen 300c2c5f6f Fix an issue on GetContainerInfo. 
I believe the issue was first introduced when we append namespace to docker
container's name. This is a temporary fix for #160.

Clayton Coleman 82bcdd3b3b Make ResourceVersion a string internally instead of uint64 
Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.

This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on
resource versions.
