Make systemd service name for kubelet use a timestamp in e2e-node tests.
**What this PR does / why we need it**:
This makes it easier to figure out which execution was last when looking at the output of `systemd list-units kubelet-*.service`.
We try to find the name of the /tmp/node-e2e-* directory and use the same timestamp if we can. Otherwise, we just call Now() again, which isn't as nice (as the unit name and directory name will not match) but will still produce unit names that will be ordered when launching multiple subsequent executions on the same host.

Fix summary_test to work when XFS is used under overlay2 and add a check for Delegate=yes missing from docker.service
**What this PR does / why we need it**:
This fixes the summary_test checks to work in cases where:
1. Docker is using overlay2 for its images with XFS as backing filesystem.
1. The systemd unit for Docker does not include Delegate=yes.
The former will break RootFs minimum usage check from summary_test, since it expects _some_ usage even though the upper layer only contains directories that are used as mount points. It turns out the XFS filesystem returns "0" blocks in the stat() result for a directory, so this breaks the test. Fix it by creating a file with some small contents in the test, so that `du` will actually return some usage.
**NOTE**: I introduced this step in the loop part of the function. It works, but maybe it's not the best... Let me know if you think we should do some small cleanup here too, I'd be happy to do that.
Regarding the latter, when `Delegate=yes` is not included in `docker.service`, then systemd might choose not to create Memory and CPU cgroups (actually, any of the resource cgroups) for the unit when it starts it. It's a bit more complicated than that, because it *does* create them if any sibling units need it, so the behavior is a bit hard to control... In any case, here we're checking on it and accepting that we might get a "nil" from cAdvisor in cases where `Delegate=yes` is missing.
Both of these issues can be found on CentOS/RHEL, that's the motivation for the fixes.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
N/A
**Special notes for your reviewer**:
/assign dashpole
**Release note**:
```release-note
NONE
```
The numbers will only be available when docker.service has its own
memory and cpu cgroups, which doesn't necessarily happen unless the unit
has Delegate=yes configured.
Let's work around that by checking the status of Delegate, in the case
where we are:
* running Docker
* running Systemd
* able to check the status through systemctl
* the status is explicitly Delegate=no (the default)
If all of those are true, let's make CPU and Memory expectations
optional.
Tested: make test-e2e-node REMOTE=true HOSTS=centos-e2e-node FOCUS="Summary API"
This is necessary to show any RootFs usage on systems where the backing
filesystem of overlay2 is xfs.
The current test only created directories (for mount points) in the
upper layer of the overlay. Outside of the mount namespace, only the
directories are visible. When running `du` on those, usually filesystems
will show some usage, but not xfs, which shows a disk usage of 0 for
directories.
Fix this by creating a file in the root directory, outside the volumes,
in order to trigger some disk usage that can be measured by `du`.
Tested: make test-e2e-node REMOTE=true HOSTS=centos-e2e-node FOCUS="Summary API"

Use curl instead of wget to fetch the CNI tarball in e2e-node test
**What this PR does / why we need it**:
Curl is more ubiquitous than wget. For instance, the GCE centos-7 and rhel-7 image families ship curl by default, but not wget.
Looking at the shell scripts under cluster/, they tend to use curl more than wget. (The ones that use wget, such as get-kube.sh, try curl first and only fallback to wget if it's not available.)
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
