Trusty: Do not create the docker-daemon cgroup

[andyzheng0831]

This is a part of fix for issue #23956. But only when #23961 is also fixed, the Jenkins testing on our image will be green.

@dchen1107 @vishh please review this. Please also add "release note" and "cherrypick-candidate" labels, and mark it as milestone 1.2, as we also need to add this correct logic in 1.2 releases.

cc/ @wonderfly @roberthbailey @fabioy FYI.

Removing label cherrypick-candidate because no release milestone was set. This is an invalid state and thus this PR is not being considered for cherry-pick to any release branch. Please add an appropriate release milestone and then re-add the label.

[andyzheng0831]

@dchen1107 I think we also need "release-note" label because I was told that every PR to be cherry picked needs such a label. The default release note for this PR is its title, which I think is accurate.

[k8s-github-robot]

Removing LGTM because the release note process has not been followed.
One of the following labels is required "release-note", "release-note-none", or "release-note-action-required"
Please see: https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/release-notes.md

There is no need to block current patch release: 1.2.2. We can include this one and a fix to test itself to next patch release. cc/ @roberthbailey @bgrant0607

@andyzheng0831 - looks like a test failed (likely flaky). Can you investigate and poke the bot?

The build failure: No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

I did some search and noticed that this happened before.

@k8s-bot unit test this issue: #IGNORE
