Unable to parse docker version

Is this a BUG REPORT or FEATURE REQUEST? (choose one):

Kubernetes version (use kubectl version):

Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.1", GitCommit:"b0b7a323cc5a4a2019b2e9520c21c7830b7f708e", GitTreeState:"clean", BuildDate:"2017-04-03T20:44:38Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.1", GitCommit:"b0b7a323cc5a4a2019b2e9520c21c7830b7f708e", GitTreeState:"clean", BuildDate:"2017-04-03T20:33:27Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

Version: 17.04.0-ce

What happened:

I found some error messages in kubelet log liking:
kubelet[51799]: E0406 16:24:23.966622 51799 container_manager_linux.go:90] Unable to parse docker version "17.04.0-ce": illegal zero-prefixed version component "04" in "17.04.0-ce"

What you expected to happen:

kublet can parse docker version "17.04.0-ce"

How to reproduce it (as minimally and precisely as possible):

Install kubelet with docker version 17.04.0-ce

Anything else we need to know:

Docker has change its release strategy and versioning scheme from v17.03.0-ce-rc1. We need to update the version verify condition to satisfy the new docker versions.

Actually, Kubernetes only supports docker version 1.10.x, 1.11.x and 1.12.x.

We don't recommend user to use version higher or lower than that range because we don't have enough test coverage on that.

As for docker new version schema, I'm fine with changing the code to tolerant new version schema, but one more remind there is no guarantee with newer docker version. :)
