fe70be9261 kubelet: revamp the pod/container naming scheme 
There are two main goals for this change.

 1. Fix the naming scheme in kubelet so that it accepts DNS subdomain
    name/namespaces correctly (#4920). The design is discussed in #3453.

 2. Prepare for syncing the static pods back to the apiserver(#4090). This
    includes

  - Eliminate the source component in the internal full pod name (#4922). Pods
    no longer need sources as they will all be sync'd via apiserver.

  - Changing the naming scheme for the static (file-, http-, and etcd-based)
    pods such that they are distinguishable when syncing back to the apiserver.

The changes includes:
  *	name = <pod.Name>-<hostname>
  * namespace = <cluster_namespace> (i.e. "default" for now).
  * container_name = k8s_<contianer_name>.<hash_of_container>_<pod_name>_<namespace>_<uid>_<random>

Note that this is not backward-compatible, meaning the kubelet won't recognize
existing running containers using the old naming scheme.

32fd331e73 Revert "Split up kubelet "source seen" logic" 
We want to sync pods from file/http/etcd sources to the apiserver, hence
differentiating sources is no longer desired.

This reverts commit 110ab6f1bd.

3ccdb8db98 kubelet: reject pods on host port conflict 
When a host port conflict is detected, kubelet should set the pod status to
fail. The failed status will then be polled by other components at a later time,
which allows replication controller to create a new pod if necessary.

To achieve this, this change stores the pod status information in a status map
upon the detecton of port conflict. GetPodStatus() consults this status map
before attempting to query docker. The entries in the status map will be removed
when the pod is no longer associated with the node.

241df2d3be kubelet: record an event with a clear reason on host port conflict 
Currently, kubelet silently ignores pods that caused host port conflict. This
commit surfaces the error by recording an event.

It also makes sure that kubelet iterates through the pods in the order of the
creation timestamp, which ensures that pods created later are ignored on
conflict.

5d6ad845cc Use Docker name (not ID) to parse Kubernetes components. 
Since the parsing function doesn't return an error all the components
returned empty strings. This caused us to enforce the MaxContainerLimit
as a global limit instead of a per-container limit.

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.

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.

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.

b131da1cf5 Sync pods asynchronously in the Kubelet. 
This makes two main changes:
- Runs syncPod in a separate Go routine (and enforces only one of those
  runs at a time).
- Uses the pod list to determine if a container should be running or
  should be killed (used to use the output of syncPod).

Since Docker pulls are synchronized by the Docker daemon we still block
on that, but pods can now be removed and prepared for starting without
blocking on long pulls.
