Try parse golang logs by default
Glog by default logs to stderr, so Stackdriver Logging shows them all as errors. This PR makes fluentd try to parse messages using glog format and if succeeded, set timestamp and severity accordingly.

We can then avoid the following warning:
```
WARNING: The '--' argument must be specified between gcloud specific args on the left and DOCKER_ARGS on the right. IMPORTANT: previously, commands allowed the omission of the --, and unparsed arguments were treated as implementation args. This usage is being deprecated and will be removed in March 2017.
This will be strictly enforced in March 2017. Use 'gcloud beta docker' to see new behavior.

Only run the systemd-journal plugin when on a platform that requests it.
The plugin crashes the fluentd process if the journal isn't present, so
it can't just be run blindly in all configurations.
It includes some performance improvements for parsing JSON (which is
very important for us, since all Docker logs are JSON) as well as a
couple new settings, like forcing of a flush of multiline logs after a
time period rather than having to wait until a new log is seen before
feeling confident flushing the previous one.
I didn't expect glog to split single log statements onto multiple lines,
but apparently it does if they're long enough. This groups them back
together appropriately.
changes to fluent-plugin-google-cloud to attach Kubernetes metadata to
logs.
Along with this, separate logs from containers in the cluster out from
logs from the daemons running on the node by instantiating two instances
of the output plugin, one which uses the new metadata (for containers)
and one which doesn't (for things like docker and the kubelet).
gunk when installing the google-fluentd agent.
Also let it log things by not redirecting to a file within the container
and only using -q (warning logs only) rather than -qq (error logs only).
