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.

rkt: Replace 'journalctl' with rkt's GetLogs() API.
This replaced the `journactl` shell out with rkt's GetLogs() API.
Fixes#26997
To make this fully work, we need rkt to have this patch #https://github.com/coreos/rkt/pull/2763

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.

rkt: Do not run rkt pod inside a pre-created netns when network plugin is no-op
This fixed a panic where the returned pod network status is nil. (Fix#26540)
Also this makes lkvm stage1 able to run inside a user defined network, where the network name needs to be 'rkt.kubernetes.io'. A temporal solution to solve the network issue for lkvm stage1.
Besides, I fixed minor issues such as passing the wrong pod UID when cleaning up the netns file.
/cc @euank @pskrzyns @jellonek @kubernetes/sig-node
I tested with no networkplugin locally, works fine.
As a reminder, we need to document this in the release.https://github.com/kubernetes/kubernetes/issues/26201
This fixed a panic where the returned pod network status is nil.
Also this makes lkvm stage1 able to run inside a user defined
network, where the network name needs to be 'rkt.kubernetes.io'.
Also fixed minor issues such as passing the wrong pod UID, ignoring
logging errors.
This reverts commit 2494c77972.
The previous commit, which launches the kubelet under `systemd-run`,
fixes an error in detecting the kubelet's cgroup stats.

rkt: Fix incomplete selinux context string when the option is partial.
Fix "EmptyDir" e2e tests failures caused by #https://github.com/kubernetes/kubernetes/pull/24901
As mentioned in https://github.com/kubernetes/kubernetes/pull/24901#discussion_r61372312
We should apply the selinux context of the rkt data directory (/var/lib/rkt) when users do not specify all the selinux options.
Due to my fault, the change was missed during rebase, thus caused the regression.
After applying this PR, the e2e tests passed.
```
$ go run hack/e2e.go -v -test --test_args="--ginkgo.dryRun=false --ginkgo.focus=EmptyDir"
...
Ran 19 of 313 Specs in 199.319 seconds
SUCCESS! -- 19 Passed | 0 Failed | 0 Pending | 294 Skipped PASS
```
BTW, the test is removed because the `--no-overlay=true` flag will only be there on non-coreos distro.
