Modify GCI mounter to enable NFSv3
In order to make NFSv3 work, mounter needs to start rpcbind daemon. This
change modify mounter's Dockerfile and mounter script to start the
rpcbind daemon if it is not running on the host.
After this change, need to make push the image and update the sha number in Changelog.

Guard the ready replica checking by server version
I fixed replica readiness checking for 1.4->1.5 upgrades by using a field that only exists in versions >=1.4.0 in #36924
This fixed a lot of issues in 1.4->1.5 upgrade testing, but did not fix 1.3->1.5 upgrade tests. I've disabled replica checking for 1.3 masters as the old logic was broken anyway.
This will not affect the 1.3 CI tests. Just 1.3 -> {1.4, 1.5} upgrade tests.
https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/kubernetes-e2e-gke-container_vm-1.3-container_vm-1.5-upgrade-cluster-new/330?log
is an example of this breakage. This is the tell-tale logs:
```console
Nov 22 09:40:50.469: INFO: 11 / 11 pods in namespace 'kube-system' are running and ready (506 seconds elapsed)
Nov 22 09:40:50.469: INFO: expected 5 pod replicas in namespace 'kube-system', 0 are Running and Ready.

Use netexec container in http lifecycle hook test.
Fixes https://github.com/kubernetes/kubernetes/issues/33636.
The original test is using `"echo -e \"HTTP/1.1 200 OK\n\" | nc -l -p 1234` as a simple http server.
However, it seems that this is not very reliable, which may response before golang thinks it should.
So we get the error:
```
I1106 06:14:13.325397 2096 logs.go:41] Unsolicited response received on idle HTTP channel starting with "HTTP/1.1 200 OK\n\n"; err=<nil>
```
This PR changes the test to use the `netexec` container which is a simple http server written by golang and used in many of our networking e2e test. It should be more reliable.
Mark 1.5 since this is fixing a 1.5 release blocking issue. Mark P0 to match the original issue.

Node E2E: Update ubuntu image to e2e-node-ubuntu-trusty-docker10-v2-image.
@sjenning Hopefully this will unblock https://github.com/kubernetes/kubernetes/pull/32577.
I built a new ubuntu trusty image with docker 10 - `e2e-node-ubuntu-trusty-docker10-v2-image`. The kernel version of the new ubuntu image is `4.4.0-47-generic`.

Mark v1.5 because this unblocks a v1.5 feature https://github.com/kubernetes/kubernetes/pull/32577.
This disables ready replica checking for 1.3 masters, but only from 1.4
or 1.5 clients. The old logic was broken anyway due to overlapping
labels with replica sets.

Fixed e2e tests for HA master.
Set of fixes that allows HA master e2e tests to pass for removal/addition master replicas.
The summary of changes:
- fixed host name in etcd certs,
- added cluster validation after kube-down,
- fixed the number of master replicas in cluster validation,
- made MULTIZONE=true required for HA master deployments, ensured we correctly handle MULTIZONE=true when user wants to create HA master but not kubelets in multiple zones,
- extended verification of master replicas in HA master e2e tests.

Test flake: ignore dig failure; wait until timeout
The intent of this test was to continue trying until the timeout has
been reached. The extra assertion makes the test fail early when it
should not.
