postsubmit results aren't showing up in testrgrid

[jlewi]

Test Grid is broken again; no results show up for post submit jobs.

I think it was working before we moved the repo to tensorflow/k8s

The entry in testgrid/config/config.yaml is

- name: tf-k8s-postsubmit
  gcs_prefix: kubernetes-jenkins/logs/tf-k8s-postsubmit

Gubernator links to

http://gcsweb.k8s.io/gcs/kubernetes-jenkins/logs/tensorflow_k8s/tf-k8s-postsubmit/11/

So I think we need to fix the location in the config file.

Setting the GCS prefix like this

- name: tf-k8s-postsubmit
  gcs_prefix: kubernetes-jenkins/logs/tensorflow_k8s/tf-k8s-postsubmit

ends up causing config_test to fail because the gcs_prefix doesn't match the test group name.

According to the gubernator docs the GCS path should not it include the repo name.

├── logs                 # periodic and postsubmit jobs live here
│   └── other_job_name   # contains all the builds of a job
│       └── build_number # contains job artifacts, as above

In #62 we had to change the GCS path to include the repo name otherwise gubernator wouldn't display the results correctly.

@krzyzacy Any idea idea what the correct fix is?
