GCI: Fix the condition for using the default image
This PR revises the condition for using the default GCI image. The old logic is not convenient for manually run e2e tests in some cases (mainly for GCI team to test custom images). The new logic by this PR is very similar to the logic in using ContainerVM. When setting distro to "gci", if master or node image is unset, we use gci-dev for it. If either is set, we respect it.
@roberthbailey @zmerlynn @dchen1107 please review it, and we should cherry pick it in release-1.2 branch. Thanks!

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.

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

Automatically download the latest stable release version of Kubernetes.
The ubuntu version of download-release.sh included in the binary release downloads the released .tar.gz file again. Right now the version of the downloaded file is manually encoded within the script. This change fetches the released version automatically, similar to the shell script available on the main Kubernetes site below:
https://get.k8s.io/
Ideally the installation on bare metal ubuntu should work with the files available in the already downloaded package.

add index template for es aggregations
This index template helps us to do es aggregations of namespace_name, pod_name and container_name. Then after doing eggs, we will get the whole name not all the spilt pieces.

Use --format='value(name)' with gcloud instead of grep/awk/cut
Fixing our fragile parsing of `gcloud` is getting old (#24746, #25159, maybe others?).
Instead, let's just get the proper output out of `gcloud` in the first place.
