1. cd to root dir before removing temp installer path. It was failing because we were trying to remove while being in the same dir.
2. Expand variables in a regular string and use it in the command. Expansion was failing in single quotes.
We need to make sure we tear down the sriov device plugin pod
should the tests fail, to avoid leaking pods in the test environment.

The available_controller creates short-lived clients to sync remote APIService
objects. These clients are constructed with HTTP transports that cannot
be cached by client-go (because client-go won't know whether the TLS configs
have dynamic functions or not), which may spam idle connections. A local
cache works because we know all the configs share the same dialer
function, and can only vary on the dynamic cert/key.
when DefaultPodTopologySpread feature is enabled
If SelectorSpreadPriority is in use, PodTopologySpread gets inevitably enabled.
When only EvenPodsSpreadPriority is in use, PodTopologySpread is configured without system defaults.

When a pod is deleted, it is given a deletion timestamp. However the
pod might still run for some time during graceful shutdown. During
this time it might still produce CPU utilization metrics and be in a
Running phase.
Currently the HPA replica calculator attempts to ignore deleted pods
by skipping over them. However by not adding them to the ignoredPods
set, their metrics are not removed from the average utilization
calculation. This allows pods in the process of shutting down to drag
down the recommmended number of replicas by producing near 0%
utilization metrics.
In fact the ignoredPods set is misnomer. Those pods are not fully
ignored. When the replica calculator recommends to scale up, 0%
utilization metrics are filled in for those pods to limit the scale
up. This prevents overscaling when pods take some time to startup. In
fact, there should be 4 sets considered (readyPods, unreadyPods,
missingPods, ignoredPods) not just 3.
This change renames ignoredPods as unreadyPods and leaves the scaleup
limiting semantics. Another set (actually) ignoredPods is added to
which delete pods are added instead of being skipped during
grouping. Both ignoredPods and unreadyPods have their metrics removed
from consideration. But only unreadyPods have 0% utilization metrics
filled in upon scaleup.
Some distributions have no default write-access to this file, which
means that it's not possible to update the file and rebuild the project
if not write-able. This patch fixes this by adding an additional
`chmod`.

Some unit tests throw this warning.
W1013 09:06:21.581870 176998 helpers.go:567] --dry-run=true is deprecated (boolean value) and can be replaced with --dry-run=client.
This patch removes the warning by using --dry-run=client instead of --dry-run=true.
The unit tests that are affected are:
make test WHAT=./vendor/k8s.io/kubectl/pkg/cmd/apply GOFLAGS=-v
make test WHAT=./vendor/k8s.io/kubectl/pkg/cmd/create GOFLAGS=-v
