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.

juju: Set apiserver advertise-address to kube-control ingress address

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.

Update COS version in Kubernetes GCE default and test
**What this PR does / why we need it**:
Set the default to cos-stable-65 (which is what we are using on GKE for latest 1.9 and 1.8) and set config-test to use cos-beta-66, so that we can get more exposure to it.
The testgrid seems to be fairly happy with these images. (both e2e-gce-cosdev-k8sdev-default and e2e-gce-cosbeta-k8sdev-default are genrally green.)

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".
