1.2.0

This release supports deployment files with environment variables that are set through fieldRef.

Previously, this was supported:

- name: GCLOUD_PROJECT
  valueFrom:
    secretKeyRef:
      name: env-variables-secret
      key: gcloud_project
- name: GCLOUD_DIAGNOSTICS_CONFIG
  value: ./utilities/trace.js

However, in 1.1.0, this would fail to parse:

- name: POD_ID
  valueFrom:
     fieldRef:
        fieldPath: metadata.name

With this release, all three formats are now supported.
