Prep for continuous Docker validation test
```release-note
Add a test config variable to specify desired Docker version to run on GCI.
```
We want to continuously validate Docker releases (#25215), on GCI. This change
adds a new test config variable, `KUBE_GCI_DOCKER_VERSION`, through which we can
specify which version of Docker we want to run on the master and nodes. This
change also patches the Jenkins e2e-runner with the ability to fetch the latest
Docker (pre)release, and sets the aforementioned variable accordingly.
Tested on my local Jenkins instance that was able to start a cluster with the latest Docker version (different from installed version) running on both master and nodes.
@dchen1107 Can you review?

Revert "Revert "GCI: add support for network plugin""
PR #27027 added the network plugin support in GCI config, but later a bug in the network plugin broke e2e tests (see issue #27118). The bug was fixed by #27141 and we have been repeatedly run the serial e2e tests more than 10 times to verify the fix. Now it should be safe to put the GCI network plugin support back.
We will first merge in the master branch and monitor the Jenkins serial tests for a while and then cherry-pick it into release-1.3 branch.

kube-up multizone: don't print scary warning
The node-count check gets confused when there are more nodes that we
launched, which is normal with KUBE_USE_EXISTING_MASTER.
This fix just suppresses the error message in that case.

Fixes and improvements to Photon Controller backend for kube-up
- Improve reliability of network address detection by using MAC
address. VMware has a MAC OUI that reliably distinguishes the VM's
NICs from the other NICs (like the CBR). This doesn't rely on the
unreliable reporting of the portgroup.
- Persist route changes. We configure routes on the master and nodes,
but previously we didn't persist them so they didn't last across
reboots. This persists them in /etc/network/interfaces
- Fix regression that didn't configure auth for kube-apiserver with
Photon Controller.
- Reliably run apt-get update: Not doing this can cause apt to fail.
- Remove unused nginx config in salt

support for mounting local-ssds on GCI
This change adds support for mounting local ssds on GCI.
It updates the previous container-vm behavior as well to
match that for GCI nodes by mounting the local-ssds under
the same path (/mnt/disks/ssdN).

Trusty: fix the 'ping' issue and fluentd-gcp issue #26379
This PR is mainly for being picking up the fix in #27016 and #27102 in trusty code, so that we can fix the issues in the release-1.2 branch for GCI. It contains two parts:
(1) Adding iptables rules to accept ICMP traffic, otherwise 'ping' from a pod does not work;
(2) Revising the code for cleaning up docker0 stuff including the bridge and iptables rules. I slightly refactor the code of starting kubelet and removing docker0 stuff before starting kubelet. The old code did it after starting kubelet but before restarting docker. I think doing it before starting kubelet is safter.

cluster/gce/coreos: Update heapster apiVersion
This fixes an inadvertant search-replace error in #26617.
The error was missed then because the search-replace issue wasn't
present in the standalone controllers, but was in all the others.
I verified that with this change heapster comes up under the default influxdb monitoring and without this change addon manager spits out validation failure errors for the heapster yaml.
