bc62096ad5 Clean up host networking plugin checks for docker manager 
We can save a docker inspect in podInfraContainerChanged() because
it's only used within the useHostNetwork() block.  We can also
consolidate some code in createPodInfraContainer() because if
the pod uses the host network, no network plugin will be involved.

Finally, in syncPodWithSyncResult() we can consolidate some
conditionals because both hairpin setup and getting the container
IP are only relevant when host networking is *not* being used.

More specifically, putting the dm.determineContainerIP() call
into the !useHostNetwork() block is OK since if no network plugin
was called to set the container up, it makes no sense to call
the network plugin to retrieve the IP address that it did not
handle.  The CNI plugin even calls back into the docker manager
to GetContainerIP() which grabs the IP from docker, which will
always be "" for host networked containers anyway.

ae2f6a833a Reduce volume of logs generated at v(3) 
Node controller is generating a huge amount of logging at v(3) that is
more appropriate for v(5). Split the log into two levels and ensure it
also ends up on one line (so grep works).

The pod manager generates a v(4) pod output on sync that always contains
a newline - since the size of the pod is so excessive in output, kick it
to v(5) for deep debugging (we're pretty happy with this loop).

fff8a7c371 kubelet: Update engine version parsing to handle semantic versioning 
This updates the dockertools.dockerVersion to use a semantic versioning
library to more gracefully support engine versions which include
additional version fields.

Previously, go-dockerclient's APIVersion struct was use which only
handles plain numeric x.y.z version strings. With #19675, the library
was now used on the Docker engine string, however it is possible for the
engine string to include include additional information for beta, rc, or
distro specific builds.

This PR also enables the TestDockerRuntimeVersion test which was
previously just a FIXME and updates it to pass, and be used to test the
version string that cause #20005.

This negates the need for fsouza/go-dockerclient#451, since even with
that change, if a user was running Docker 1.10.0-rc1, this would cause
the kubelet to report it as simply 1.10.0.

a7b07c01df Update container runtime to properly report the engine and version 
This address a TODO when collecting the node version information so it
will properly report the configured runtime and its version. Previously,
this was hardcoded to "docker://" and the docker version, and would show
"docker://1.9.1" even when the kubelet was configured to use rkt.

With this change, it will use the runtime's Type() and Version() data.

This also changes the container.Runtime interface to add an APIVersion()
method. This can be used when the runtime has separate versions for the
engine and the API, such as with Docker. The Docker minimum version
validation has been updated to use APIVersion(), and
DockerManager.Version() now returns the engine version.

2eb17df46b kubelet: independent pod syncs and backoff on error 
Currently kubelet syncs all pods every 10s. This is not preferred because
 * Some pods may have been sync'd recently.
 * This may cause all the pods to be sync'd at once, causing undesirable
   CPU spikes.

This PR replaces the global syncs with independent, periodic pod syncs. At the
end of syncing, each pod worker will enqueue itslef with a future timestamp (
current time + sync interval), when it will be due for another sync.
 * If the pod worker encoutners an sync error, it may requeue with a different
   timestamp to retry sooner.
 * If a sync is triggered by the update channel (events or spec changes), the
   pod worker would enqueue a new sync time.

This change is necessary for moving to long or no periodic sync period once pod
lifecycle event generator is completed. We will still rely on the mechanism to
requeue the pod on sync error.

This change also makes sure that if a sync does not succeed (either due to
real error or the per-container backoff mechanism), an error would be propagated
back to the pod worker, which is responsible for requeuing.

a263c77b65 Refactor liveness probing 
This commit builds on previous work and creates an independent
worker for every liveness probe. Liveness probes behave largely the same
as readiness probes, so much of the code is shared by introducing a
probeType paramater to distinguish the type when it matters. The
circular dependency between the runtime and the prober is broken by
exposing a shared liveness ResultsManager, owned by the
kubelet. Finally, an Updates channel is introduced to the ResultsManager
so the kubelet can react to unhealthy containers immediately.

eeb4eeb17c Move pause and fluentd-elasticsearch to GCR v2. 
This scopes down the initially ambitious PR:
https://github.com/kubernetes/kubernetes/pull/14960 to replace just
`pause` and `fluentd-elasticsearch` to come through `beta.gcr.io`.

The v2 versions have been pushed under new tags, `pause:2.0` and
`fluentd-elastisearch:1.12`.

NOTE: `beta.gcr.io` will still serve images using v1 until they are repushed with v2.  Pulls through `gcr.io` will still work after pushing through `beta.gcr.io`, but will be served over v1 (via compat logic).

ed021fed4c Port forwarding fixes 
Correct port-forward data copying logic so that the server closes its
half of the data stream when socat exits, and the client closes its half
of the data stream when it finishes writing.

Modify the client to wait for both copies (client->server,
server->client) to finish before it unblocks.

Fix race condition in the Kubelet's handling of incoming port forward
streams. Have the client generate a connectionID header to be used to
associate the error and data streams for a single connection, instead of
assuming that streams n and n+1 go together. Attempt to generate a
pseudo connectionID in the server in the event the connectionID header
isn't present (older clients); this is a best-effort approach that only
really works with 1 connection at a time, whereas multiple concurrent
connections will only work reliably with a newer client that is
generating connectionID.
