In order to test eviction related functionality it will be convenient
to have reasonable eviction defaults.
At this moment exactly same flags are used by GCE environment
kubelet will have a following flag:
--eviction-hard=memory.available<100Mi,nodefs.available<10%

fix log message to include ds name
The pod name is never set because newPod is created a couple lines up without a name. Instead log the name and namespace of the ds which the pod is created from.
also bump the log level because reasons loop get's hit fairly often and does not indicate a bug.

**What this PR does / why we need it**:
Consider the following code block,
```
err := myfunc()
agg := errors.NewAggregate([]error{err})
fmt.Println("aggregate error is %v", agg)
```
If the `err` is **nil**, then it will cause a panic:
```
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
panic: runtime error: invalid memory address or nil pointer dereference

```
The root cause is that [aggregate.Error()](https://github.com/kubernetes/kubernetes/blob/master/pkg/util/errors/errors.go#L47) doesn't check if error list contains nil.
We can blame the user didn't check if `err` is nil before passing it to
```
errors.NewAggregate([]error{err})
```
but I think we can check again inside in case of user forget to check outside.

Make a vSphere cluster the failure_zone
vSphere cloud provider returns the FailureZone as Cluster, if the VM belongs to a ResourcePool under a Cluster.
fixes: #30933
* Currently the vSphere cloud provider treats Datacenter as the failure
Zone. This doesn't necessarily work since in the current implemention
Kubernetes nodes cannot span Datacenters.
* This change introduces Clusters as the failure zone, while treating
Datacenters as Regions
* Also updated tests for Zones

Fix named pipe in kubectl zsh completion
This PR fixes#28049
Though my zsh version > 5.0, I still got the problem. So, I think we need this fix.
---
### Env
```
OS: Ubuntu 14.04
$ zsh --version
zsh 5.0.2 (x86_64-pc-linux-gnu)
```
### A simple DEMO to show the root cause
In zsh and bash, a multi-line named pipe, who is wrapped by parenthesis, is possible to mismatch the "right parenthesis", even that parenthesis is in a here-document.
The following script was going to use `sed` to print the text in the 'BASH_COMPLETION_EOF' here-document.
> * I made the `sed` simpler. As you can see, `sed` actually does nothing here. It just prints what it gets from `<<`). In real [`pkg/kubectl/cmd/completion.go`](https://github.com/kubernetes/kubernetes/blob/v1.3.5/pkg/kubectl/cmd/completion.go#L246-L258), `sed` will do some text replacement, changing bash functions to zsh functions. But that is not the point of the problem.
> * I use `cat <(...)` to replace the `source <(...)`.
> In this way, we can see how named pipe works.
run-bad.zsh:
```bash
#!/usr/bin/zsh
cat <(sed -e 's/foo/bar/g' <<'BASH_COMPLETION_EOF'
aaa='aaa'
case aaa in
'aaa') # <- This ')' is in a here-document, but it is handled by named pipe by mistake.
echo 'yes'
;;
esac
BASH_COMPLETION_EOF
)
```
> Output:
> ```
> ./run-bad.zsh
> aaa='aaa'
> case aaa in
> 'aaa'yes <- You can see the here-document `echo yes` has been executed!!!
> ./run-bad.zsh:8: parse error near `;;'
> ```
The named pipe `<(sed ...` "eats" the `)`, which should belong to `case aaa in 'aaa')`. So that the named pipe ends earlier than expectation. The left zsh code is broken, it fails.
### Here's the fix
Move the code into a function, and use an inline named pipe.
run.zsh:
```bash
#!/usr/bin/zsh
print_sed_result() {
sed -e 's/foo/bar/g' <<'BASH_COMPLETION_EOF'
aaa='aaa'
case aaa in
'aaa')
echo 'yes'
;;
esac
BASH_COMPLETION_EOF
}
cat <(print_sed_result) # <- Use an inline named pipe
```
> Output:
> ```
> ./run.zsh > stack@docker-dev01
> aaa='aaa'
> case aaa in
> 'aaa')
> echo 'yes'
> ;;
> esac
> ```
Now, the here-document and named pipe work correctly.

Add e2e test for Source IP preservation (pod to service cluster IP)
Working on #27134.
This PR added the e2e test for source ip preservation (pod to service cluster IP) in service.go. Test scenario described as below:
- Pick two different nodes in cluster.
- Create a clusterIP type service.
- Create an echo server, which echoes back client IP, to be part of the service.
- Create a client on another node. Hit the server through service cluster IP.
- Verify the source IP.

**What this PR does / why we need it**:
This fix updates the build docs (`build/README.md`) to include the path of `build/` for shell scripts (like `run.sh`, `shell.sh`).
The reason is that while trying to follow the `build/README.md` to build the kubernetes, it is not obvious that all the scripts, e.g., `run.sh make`, `shell.sh`, etc. needs to be executed from the root directory (vs. executed from the `build/` directory).
In other words, the executation should be:
```
build/run.sh make
build/make-clean.sh
...
```
This fix adds `build/` so that it is easy for user to follow the steps.
