crictl logs should share code from kubelet.

[Random-Liu]

Currently, we copy all the code from kubelet.

We should make the code in kubelet to be a CRI log parsing library. And import the library in crictl.

[yanxuean]

Do you mean cri-tools/cmd/crictl/logs.go?

[Random-Liu]

Yeah, most of the code there is the same with https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/kuberuntime/kuberuntime_logs.go

[yanxuean]

I will fix it late.

@Random-Liu help:)
The cri-tools depend on k8s.io/kubernetes/pkg/kubelet/kuberuntime.
The kuberuntime depend on these as below:

k8s.io/apiextensions-apiserver
k8s.io/apiserver
k8s.io/metrics

The problem is how do I get the version of k8s.io/apiextensions-apiserver corresponding to k8s.io/kubernetes?

I checked kubernetes/Godeps/Godeps.json, there is not answer.

@yanxuean @Random-Liu We need to make kubelet logs a lib first. Let's make the code in kubelet to be a CRI log parsing library.

[yanxuean]

Agree. Now we need import kuberuntime. It is too complex.

[yanxuean]

The logs is indepent function.
