provision kubelet config file for GCE instead of deprecated flags
Many Kubelet flags are now deprecated in favor of the versioned config file format. This PR adopts the versioned config file format in our cluster turn-up scripts.
```release-note
cluster/kube-up.sh now provisions a Kubelet config file for GCE via the metadata server. This file is installed by the corresponding GCE init scripts.

cluster/gce/list-resources.sh: also list stackdriver logging sinks
**What this PR does / why we need it**: we seem to be logging stackdriver logging sinks on GCE, likely because we're not keeping track of them. (ref https://github.com/kubernetes/test-infra/issues/7295)
This doesn't fix the leaks, but it'll hopefully help us detect when that happens.

Reimplement migrate-if-needed.sh in go
The `migrate-if-needed.sh` script was already partially implemented in go (see the attachlease and rollback sub-dirs), but was still unnecessarily difficult to understand and test. This closely reimplements the original logic but with improved code structure, error handling and testing.
Where possible, go code that was previously executed as separate binaries is now statically linked into a single 'migrate' go cobra CLI app, which is then thinly wrapped by`migrate-if-needed.sh`.
There are numerous additional improvements that need to be made, but will be submitted in future PRs. This PR is focused on achieving parity with the pre-existing functionality and introducing some much needed test coverage, in particular HA cluster upgrade test coverage.
It appears that the `attachlease` and `rollback` go binaries are no longer needed as standalones and so I have consolidated them into the new `migrate` go binary. Other than that, this change aims to be 100% backward compatible.

1. I am starting off with migrating images under k8s/test/images/volumes-tester.
2. I did not move ceph and nfs images since they are marked for [deprecation and removal](https://github.com/kubernetes/kubernetes/tree/master/test/images/volumes-tester). Let me know if we want them moved as well.
3. I have made a copy of the images in gcr.io/kubernetes-e2e-test-images so the references are not broken post the PR merge. Will work on removing the images from k8s.gcr.io once this change sticks.
I find it useful to have the kernel logs available for searching, for example that's the only place you can see processes killed when they hit memory limits.

When using custom network with IP-alias, use the former's subnet for the latter too
Currently, when we're using custom subnet and ip-alias simultaneously, the cluster fails to come up.
The reason is because we're creating a subnet in the former with one name, but expecting a differently named subnet for the latter.
This is causing [continuous failures in our 100-node job](https://k8s-testgrid.appspot.com/sig-scalability-gce#gce) where I recently turned both of them on.

**What this PR does / why we need it**:
When we switched to an ingress daemonset, we didn't account for older installs. The api version changed on version 1.9, so anything pre-1.9 needs a different version. This PR makes the api version a template so we can change it depending on the version of k8s installed.

Change HAIRPIN_MODE to hairpin-veth as default
**What this PR does / why we need it**:
Change the default HAIRPIN_MODE back to "hairpin-veth".
It was previously "promiscuous-bridge" in order to workaround a kernel bug which deadlocked the machine when hairpin-veth was used. (#27498)
After some thorough manual testing on ubuntu clusters, we feel confident now that the kernel bug is fixed so we should switch back to using hairpin-veth. This will allow us to clean up some ebtables rules that were put in place to make "promiscuous-bridge" work properly.
Once this change goes in, we need to carefully monitor our e2e tests to make sure the bug has not resurfaced.
**Release note**:
```release-note
In a GCE cluster, the default HAIRPIN_MODE is now "hairpin-veth".
```

In order to use -n, the value needs either be quoted or [[ .. ]] block
has to be used. Fix the comparisons that way.
To verify, consider this (analogous) script:
#!/bin/bash
subnetwork_url=""
if [ -n ${subnetwork_url} ]; then
echo "foo"
fi
if [[ -n ${subnetwork_url} ]]; then
echo "bar"
fi
Here "foo" is echoed by the script, even though the variable
subnetwork_url has a zero-length value.
In shell scripts inside [[ .. ]] blocks, ">" is a string comparison operator.
The "attempt" number comparison works (most likely by accident) because the max
number of attempts is below 10. Change to -gt operator.
