Thanks for your awesome contribution!

Could you please sign the CLA

BTW, do you run dep prune to reduce the size of vendor?

[jetmuffin]

@gaocegege there are still some problems on dependencies, I'm working on it now..

[gaocegege]

We could add hack as ignore files for gometalinter in Travis CI, because it is not the code used by the operator.

[jetmuffin]

@gaocegege I tried to reduce the size of vendor, but it seems necessary to set up a server with generated model and api routing information according to kubernetes/kube-openapi#13, so many packages of k8s.io/apiserver are required.

[gaocegege]

@jetmuffin Thanks, we could keep it if it is necessary.

@ddysher We have a discussion about whether the code should be in the upstream, so PTAL.
