make GCI image detection robust
This change makes sure that in case we roll back a released GCI image, the image detection logic picks a correct active image.

Allow disabling of dynamic provisioning
Allow administrators to opt-out of dynamic provisioning. Provisioning is still on by default, which is the current behavior.
Per a conversation with @jsafrane, a boolean toggle was added and plumbed through into the controller. Deliberate disabling will simply return nil from `provisionClaim` whereas a misconfigured provisioner will continue on and generate error events for the PVC.
@kubernetes/rh-storage @saad-ali @thockin @abhgupta
Many integration tests delete all keys in etcd as part of their cleanup.
To run these tests in parallel we must run several etcd daemons, each on
different port and pass etcd url to the test suite.

Fill PV.Status.Message with deleter/recycler errors.
Instead of empty `Message` `kubectl describe pv` now shows:
```
Name: nfs
Labels: <none>
Status: Failed
Claim: default/nfs
Reclaim Policy: Recycle
Access Modes: RWX
Capacity: 1Mi
Message: Recycler failed: Pod was active on the node longer than specified deadline
Source:
Type: NFS (an NFS mount that lasts the lifetime of a pod)
Server: 10.999.999.999
Path: /
ReadOnly: false
```
This is actually a regression since 1.2

Allow emitting PersistentVolume events.
Similarly to Nodes, PersistentVolumes are not in any namespace and we should
not block events on them. Currently, these events are rejected with
`Event "nfs.145841cf9c8cfaf0" is invalid: involvedObject.namespace: Invalid value: "": does not match involvedObject`

Deleting federation-push.sh
This has bit me a few times. And based on my discussions with @madhusudancs has bit him as well.
Running federation-push.sh doesnt work anymore.
Running build/push-federation-images.sh does the right thing.
They were both trying to do the same thing anyway.
Our documentation (https://github.com/kubernetes/kubernetes/blob/master/docs/devel/e2e-tests.md#federation-e2e-tests) suggests running push-federation-images.sh.

Update to dnsmasq:1.3 and make hyperkube always use the latest addons
This bumps dnsmasq to a version that works on all architectures: https://github.com/kubernetes/contrib/pull/1192 (which have to be pushed first indeed)
Also I removed the manifests in hyperkube addons in favor for machine-generated ones, which will avoid mistakes.
This one is required for `v1.3`, so it has to be cherrypicked I think...
It makes docker and docker-multinode addons work again...
(Yes, we'll probably get rid of docker in favor for minikube, but we'll have to have it in this release at least)

Node E2E: add termination message test
Based on #23658.
This PR:
1) Cleans up the `ConformanceContainer` a bit
2) Add termination message test
This test proves #23639, without #23658, the test could not pass.

AWS kube-up: set net.ipv4.neigh.default.gc_thresh1=0 to avoid ARP over-caching
This works around a linux kernel bug with overly aggressive caching of
ARP entries, which was causing problems when we reused IP addresses in
VPCs, for example with an ASG in a relatively small subnet.
See #23395 for more explanation.

ObjectMeta, ListMeta, and TypeMeta should implement their interfaces
Make unversioned.ListMeta implement List. Update all the *List types so they implement GetListMeta.
This helps avoid using reflection to get list information.
Remove all unnecessary boilerplate, move the interfaces to the right
places, and add a test that verifies that objects implement one, the
other, but never both.
@ncdc @lavalamp this supercedes #26964 with the boilerplate removed. Added tests

kubelet/kubenet: split hostport handling into separate module
This pulls the hostport functionality of kubenet out into a separate module so that it can be more easily tested and potentially used from other code (maybe CNI, maybe downstream consumers like OpenShift, etc). Couldn't find a mock iptables so I wrote one, but I didn't look very hard.

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?
cc/ @andyzheng0831 for changes in `cluster/gce/gci/helper.sh`, and @ixdy @spxtr for changes to the Jenkins e2e-runner
