prevent nil pointer when starting controllers before running the shar…
Fixes https://github.com/kubernetes/kubernetes/issues/25643.
https://github.com/kubernetes/kubernetes/pull/23795 changed initialization order, so the controller isn't guaranteed to be present at startup.
@mqliang @wojtek-t I'm pretty sure that we're not guaranteed to get back the correct `cache.Indexer` or `cache.Store` either. I'll look at re-plumbing the `AddIndexer` path to use the same instance so that its safe to use again.

AWS: More support for ap-northeast-2 region
Issue #24446
The new AWS region for Seoul, Korea (ap-northeast-2)
was launched in January 2016
https://aws.amazon.com/blogs/aws/now-open-aws-asia-pacific-seoul-region/
But it requires a few changes.
To test:
```
export KUBERNETES_PROVIDER=aws
export KUBE_AWS_ZONE=ap-northeast-2a
export MASTER_SIZE=t2.medium
export NODE_SIZE=t2.medium
export NUM_NODES=4
cluster/kube-up.sh
```
I assigned the AMIs by checking the specific version used from `ap-northeast-1`,
and finding the same image with the same datestamp.

Newrelic daemonset
1. base64 on Mac does not support the **wrap** option. Easy to support on both Mac and Linux by using **tr** to remove the newline.
2. DaemonSet definition does not conform to latest schema:
> $ kubectl create -f ./newrelic-daemonset.yaml
error validating "./newrelic-daemonset.yaml": error validating data: found invalid field privileged for v1.PodSecurityContext; if you choose to ignore these errors, turn validation off with --validate=false

GCI/Trusty: Fix an issue in using 'find' commands
This PR makes the logic of 'find' command consistent with the 'cp' command afterwards, i.e., only check one layer of a given dir. Without this fix, we have seen a recent breakage after PR #25309 added the file cluster/addons/fluentd-elasticsearch/es-image/template-k8s-logstash.json. The 'find' command discovers this json file, but the 'cp' command fails.
@roberthbailey @dchen1107 @zmerlynn please review this fix, and mark it as a cherry pick candidate. I already verified this fix can resolve the breakage.

GCI: Enable the log of upstart jobs
This PR enables the log of upstart jobs in master.yaml and node.yaml. By default, log of upstart jobs are enabled in Trusty and placed in /var/log/upstart, but not enabled in GCI. This change explicitly directs the log to the system logger. For trusty, they are in /var/log/syslog file. In GCI, we can check it using "journalctl". This change will be useful for debugging if cluster initialization fails.
@roberthbailey @maisem @dchen1107 please review it. This will be useful for issues like #23634. We should also cherry pick it in release-1.2

test: Call forgotten resttest test
PR #3789 introduced this test, but it was never called.
This test was created, but never called.
Written, but never run.
It has neither flaked nor asserted. At its inception it was deserted.
My change gives this test a chance, to at long last finally pass.
The resttest stuff is a bit complicated and I'm not totally sure I put it in the right place @smarterclayton, want to double check this change makes sense?
