refresh volumes logic

[lminzhw]

After this PR merged, the volume behavior would change to this.

---

Before all, we have a job like this:

metadata:
  generateName: lm-volume-
  name: lm-volume-drhwm
spec:
  volumes:
  - mountPath: /mnt11
  - mountPath: /mnt21
    volumeClaimName: lm-pvc
  - mountPath: /mnt31
    volumeClaim:
      accessModes:
        - ReadWriteOnce
      resources:
        requests:
          storage: 1Gi

• The first volume would be an emptyDir for all container at /mnt11.
• The second volume would mount lm-pvc to /mnt21.
• The third volume would create a pvc following volumeClaim with name format {jobname}-volume-{randomStr} and mount it to /mnt31.

---

So the info recorded in controlledResources would be like this

status:
  controlledResources:
    volume-emptyDir-lm-volume-drhwm-volume-7hmf0d7qfonv: lm-volume-drhwm-volume-7hmf0d7qfonv
    volume-pvc-lm-pvc: lm-pvc
    volume-pvc-lm-volume-drhwm-volume-4t5agfb78vfj: lm-volume-drhwm-volume-4t5agfb78vfj

Hey @lminzhw,
Something went wrong with the build.

TravisCI finished with status errored, which means the build failed because of something unrelated to the tests, such as a problem with a dependency or the build process itself.
