Move userspace code to sub-package in proxy.

Revert "Add e2e test monitoring current container resource usage"

Moves the userspace code in proxy to a sub-package and adds the
ProxyProvider interface.

This is in preparation for landing an implementation of
https://github.com/GoogleCloudPlatform/kubernetes/issues/3760, which
will mostly be in another sub package for iptables.

Convert underscore to dash

Add Save, SaveAll, Restore, RestoreAll to pkg/util/iptables

also put TODO for unit tests, move defer file deletion until after file
creation error is checked.

Reverting "Updating swagger-ui to the latest version #10902"

Add e2e test monitoring current container resource usage

Kubectl describe command accepts a filename param

kubelet: Add 'image pulling' event. Refactor dockerManager.createPodInfraContainer()

Improve architecture diagram readability

Add support for request

Add QoS support on node

QoS proposal

Adds utility wrappers for `iptables-save` and `iptables-restore` to the
iptables Interface in pkg/util/iptables. Also const’s command strings.

This reverts commit 3020fe8ebfbb9ee0a1f76fd9afb09b8d577e420e, reversing
changes made to de15703af096cad38d40361d696e236d197895cf.

Replace the trunk of pull image code with dockerManagner.pullImage().
Also add tests to verify the image pulling/pulled events.

Don't wrongly identify endpoint addresses only due to equal IP

Add age column for all resources when using 'kubect get'

status hook for the container network

Since it takes a while (1-2mins) for kubelet to pulling a big image
(>500MB). Just showing "Pending" for pod status is not very helpful.

This commit introduces a "pulling" event, and inserts it before the
kubelet starts to pull an image.

Replace usage of ifup and ifdown in the reboot test with ifconfig

Bump fsouza/go-dockerclient godep

All binaries in kubenretes show `-` for help and seem to expect `-`. Although
`_` also works. The inconsistencies across the codebase using - and _
result in difficultly using things like grep to find things that need to
be changed.

Revert "Move prioritizer function EqualPriority to package priorities"

Move prioritizer function EqualPriority to package priorities

Event test client may or may not be namespaced

Add a test for HTTP health checks that validates healthy pods stay up

Instead of using human-oriented output, use -o template to
validate cluster in order to avoid error caused by column change.
