Exporting container_memory_kernel from memory.kmem.usage_in_bytes

[thomasf1234]

In response to #2138

Through prometheus testing the following relationship seems to be present:

container_memory_usage_bytes == container_memory_rss + container_memory_cache + container_memory_kernel

Hi @thomasf1234. Thanks for your PR.

I'm waiting for a google or kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Is this true? What about the result? Seems not completed.

Hi what is the progress of this? What about the result?

[dashpole]

Looks like the CLA was never signed for this, so i'm not able to accept it. This seems like a reasonable change though, so if anyone wants to pick this up, I think it should be acceptable.

@dashpole I'll take a shot at this.

@danishprakash I am no longer the maintainer of cAdvisor, so you'll need to work with @bobbypage
