Add support to ingest log entries to Stackdriver against new "k8s_container" and "k8s_node" resources.
**What this PR does / why we need it**:
**Which issue(s) this PR fixes**
Fluentd 0.14 has some memory leak issues that caused the e2e tests to be flaky. Downgrading to v0.12.
**Special notes for your reviewer**:
We never released any previous version with Fluentd v0.14. Only upgraded it very recently. So this downgrading is not visible to users.
**Release note**:
```release-note
Add support to ingest log entries to Stackdriver against new "k8s_container" and "k8s_node" resources.
