The kube etcd and discovery pods are set to unconfined_t in
order to avoid disabling selinux, but the correct type for
an unconfined container is spc_t. For more information, see

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.

Change stickyMaxAge from seconds to minutes, fixes issue #35677
**What this PR does / why we need it**: Increases the service sessionAfinity time from 180 seconds to 180 minutes for proxy mode iptables which was a bug introduced in a refactor.
**Which issue this PR fixes**: fixes#35677
**Special notes for your reviewer**:
**Release note**:
``` release-note
Fixed wrong service sessionAffinity stickiness time from 180 sec to 180 minutes in proxy mode iptables.
```
Since there is no test for the sessionAffinity feature at the moment I wanted to create one but I don't know how.

HA master, fixed replica name when creating load balancer.
HA master, fixed replica name when creating load balancer. Was broken when replica
w/o suffix was no longer in the cluster.
Gluster server needs a filesystem that supports extended attributes for its
data. Some distros (Debian, Ubuntu) ship Docker that runs containers on aufs,
which does not support extended attributes and therefore Gluster server fails
there.
We can use tmpfs for Gluster server data volumes instead of a directory inside
the container.

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.

Add more logging around Pod deletion
After this PR we'll have at least V(2) level log near all Pod deletions.
@saad-ali - this is required by GKE to help with diagnosing possible problem.

Check sysfs Type instead of Device
Some distribution uses "none" device to mount "sysfs" type, so kube-proxy needs to list mount points and check "types" instead of "device".

Change sysfs mountpoint tests from Device to Type to be able to find sysfs mountpoint on "none" device

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.
