Add toleration to fluentd daemonset to make it run on master
Because of https://github.com/kubernetes/kubernetes/pull/41172 fluentd pods stopped being allocated on master node.
This PR introduces toleration for master taint for fluentd.

Unfortunately, we don't have e2e tests to ensure that master logs are being ingested. This problem is a great signal to work on https://github.com/kubernetes/kubernetes/issues/41411
These files have been created lately, so we don't have much information
about them anyway, so let's just:
- Remove assignees and make them approvers
- Copy approves as reviewers

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.

Make fluentd pods critical
Related to https://github.com/kubernetes/kubernetes/issues/38322
Make fluentd critical so it will be evicted with less probability.

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.
