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.

Remove mapping to /host/lib from fluentd-gcp container.
**What this PR does / why we need it**:
This mapping is no longer needed since fluentd-gcp v2.0.16, in which it started using a container image based on Debian Stretch, in which the systemd libraries already include support for all the supported
compression algorithms.
The `/run.sh` in the image no longer accesses `/host/lib` anyways, so let's stop mapping it here.

Find most recent modified date for fluentd buffers recursively.
Fixes#60762
**What this PR does / why we need it**:
Due to updates in Fluent v0.14, the buffers directory modified date is no
longer updated when files inside the directory are changed. Therefore we
must find the most recent modified date recursively to fix liveness probe.
