Run etcd 2.0.5 in a pod

[ArtfulCoder]

@zmerlynn

This PR should work correctly since we added some robustness to kube-addons creation logic with the retries #6200

[zmerlynn]

Is this image on ContainerVM now, or should we get it onto gcr.io?

[dchen1107]

This shouldn't be in ContainerVM image since we still support other internal users.

[zmerlynn]

I'm okay with merge as-is so we can start to get some run-time. Can you file a follow-on issue to move this to gcr.io quickly, though, so all infrastructure is off docker hub?

[zmerlynn]

LGTM except that question.

[dchen1107]

LGTM. Can you run e2e test against this change?

[dchen1107]

This is revert-of-revert-of-#4442

[dchen1107]

Please run e2e tests and post the result here. Network test was failed due to

1. Networking test timing out on Jenkins #5629 (comment)
   which is fixed in test itself.

2. apiserver is not response

My second test run finished
There were two failures, both related to PD tests
[It] verify monitoring pods and all cluster nodes are available on influxdb using heapster.

INFO: failed to query list of pods from influxdb. Query: "select distinct(pod_id) from /cpu./", Err: expected only one series from Influxdb for query "select distinct(pod_id) from /cpu./". Got []

[It] should schedule a pod w/ a RW PD, remove it, then schedule it on another host
INFO: Couldn't delete PD. Sleeping 5 seconds

[ArtfulCoder]

of the two, the first is failing on HEAD as well.

The second is failing on a "gcloud compute disks delete" command even after though the pod holding the pd has been killed.

I believe these are not related to my change.
So we should be good to go to merge this change.

@eparis ^ FYI.

[zmerlynn]

Merging to get some soak time in Jenkins.

[dchen1107]

Great!

@aveshagarwal

Can you check out how he docker-i-fied etcd and see if there is anything here we want to grab/contribute?

[aveshagarwal]
