Need to add bracket in the tag for sig-windows. Also fix an issue: for
current testing structure, it first init driver and then set up the
framework. So when initialize the driver, it does not know what OS is
and we can not set up the capabilities correctly. Instead we have to add
all the capabilities and supported fs types including both linux and
windows. Later in the code, we will check the Node OS and decide how to
run the test.
The test [sig-node] PreStop should call prestop when killing a pod
[Conformance] use the nettest image for testing, but it turns out
that this image is configured to listen in the address 0.0.0.0.
Removing the address from the function http.ListenAndServe makes
it start listening on both IPv4 and IPv6 addresses.

Current e2e tests for the Container Lifecycle Hooks weren't
using brackets for the IPv6 URL addresses per RFC2732, thus those
tests were failing.
This patches add brackets to the target URL if it's an IPv6 address.

The test [k8s.io] Probing container [It] should not be restarted with a
/healthz http liveness probe [NodeConformance] [Conformance]
fails because it's using a nginx image that's spawns a server that's
only listening on IPv4 by default.
Switching to an image like TestWebserver that's listening in IPv4 and IPv6 by default
allows the test to run on IPv4 and IPv6 environments.

Current regex used in the Downward e2e API tests is matching only
IPv4 addresses, consequently those tests fails with IPv6 clusters.
This patch modifies the regex to match ipv4 and ipv6 addresses.

And add a corresponding flag in kubectl (for apply), even though the
value is defaulted in kubectl with "kubectl".
The flag is required for Apply patch-type, and optional for other PATCH,
CREATE and UPDATE (in which case we fallback on the user-agent).
Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`
Windows containers do not include a route to the GCE metadata server by
default. This check is causing the "DNS should provide DNS for the
cluster" test to fail for clusters with Windows nodes
(https://testgrid.k8s.io/sig-windows#gce-windows-master&width=20).
Tested that this works by running "DNS should provide DNS for the
cluster" against an e2e cluster with Windows nodes brought up on GCE.
Current IPv6 e2e test for external connectivity is using a
domain address (google.com) as target.
However, the same IPv4 test uses the well known Google DNS address
8.8.8.8.
We should be coherent in the testing, this patch changes the target to use
the Google IPv6 DNS address 2001:4860:4860::8888.
