test/images/mount-tester: ensure exec binary is o+rx
The `mount-tester` image is currently used as a base layer for other
test images (like `mounttest-user`) which perform uid/gid changes.
However, the binary built in here just follows local umask, and currently is
```
-rwxr-x--- 1 root root 2052704 May 19 2016 mt
```
This commit adds an explicit chmod on the binary to make sure uid/gid
tests can still run it as "others".

Use tmpfs for gluster-server container volumes.
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. ~~This expects that host's /tmp is tmpfs, which is true for Debian, Ubuntu, RHEL, CentOS and Fedora.~~
I reworked it to mount tmpfs inside the container, the server pod is privileged.
And *after* this PR is merged and new Gluster server container image is pushed we need to bump the image version in https://github.com/kubernetes/kubernetes/blob/master/test/e2e/volumes.go#L407
Edit: I also fixed Gluster server Dockerfile, it was not working at all.

We can use tmpfs for Gluster server data volumes instead of a directory inside

Fixed gcloud command in logs-generator makefile
I grepped through the code looking for `gcloud` and `push` commands and only found one Makefile missing the `--`. I added it.

test-images: server address is now configurable
This commit perform changes discussed in #32128
Should be merged before #35301
cc: @pskrzyns
We can then avoid the following warning:
```
WARNING: The '--' argument must be specified between gcloud specific args on the left and DOCKER_ARGS on the right. IMPORTANT: previously, commands allowed the omission of the --, and unparsed arguments were treated as implementation args. This usage is being deprecated and will be removed in March 2017.
This will be strictly enforced in March 2017. Use 'gcloud beta docker' to see new behavior.

IPerf container to support network perfomance testing
Simple iperf container.
Issue:
We want to run iperf from the e2e tests for a network baseline, but there are no gcr images for this.
Solution:
Curate our own iperf container from source in kubernetes and copy it as a top level microservice. So long as these are injected into GCR, we can then run this container from the e2e tests.
cc @sig-testing this can be used along side #22869
- document needed packages in hostexec image
- add RunHostCmdOrDie
- kube-proxy e2e: port from ssh to hostexec
- use preset NodeName to schedule test pods to different nodes
- parallel launch of pods
- port from ssh to hostexec
- add timeout because nc might block on udp
- delete test container without grace period
- PrivilegedPod e2e: port from ssh to hostexec
- NodePort e2e: port from ssh to hostexec
- cluster/mesos/docker: Enable privileged pods
Since this is a container service port anyways, "insecure" is a bit of
a red herring. There's no real security relevance to the incoming port
numbers for the NFS server pod.
This lets us get rid of the examples/nfs/exporter Docker build
(@jsafrane's personal image).
A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.
From RFC 3530:
During the grace period, the server must reject READ and WRITE operations
and non-reclaim locking requests (i.e., other LOCK and OPEN operations)
with an error of NFS4ERR_GRACE.
That basically means that all open() calls from clients are blocked until the
grace period is over (90 seconds by default).
We want the grace period as low as possible to speed up the tests. '10'
seconds were tested on Fedora 21 and Ubuntu 15.04 as the hosts.
The test image is rebased to Fedora in order to get 'rpc.nfsd -G <n>' option,
Ubuntu does not support it.
