This only applies to gce kube-up. 60 seconds of open connection should
be sufficient for anything that we should be downloading. The release
tar is currently 255M.

Fixed mounting with containerized kubelet
`NsenterMounter.IsLikelyNotMountPoint()` should return `ErrNotExist` when the
checked directory does not exists - the regular mounted does this and
some volume plugins depend on this behavior.
See for example: https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/aws_ebs/aws_util.go#L72

Implement a streaming serializer for watch
Changeover watch to use streaming serialization. Properly version the
watch objects. Implement simple framing for JSON and Protobuf (but not
YAML).

Add godoc to kubelet/volumes.go
Noticed that `mountExternalVolumes`, of all things, was missing Godoc while working w/ @screeley44. Decided to add some tonight since I have been making noise about grokkability of the kubelet lately.

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
This makes it easier to determine which tests cause particular suites to
fail.
All static HTML pages are now generated by one invocation of gen_html.py.
- make index include good/flake/fail numbers for each link
- consistently use % for string interpolation

e2e: adapt kubelet_perf.go to use the new summary metrics API
This commit switch most functions in kubelet_stats.go to use the new API.
However, the functions that perform one-time resource usage retrieval remain
unchanged to be compatible with reource_usage_gatherer.go. They should be
handled separately.
Also, the new summary API does not provide the RSS memory yet, so all memory
checking tests will *always* pass. We plan to add this metrics in the API and
restore the functionality of the test.

Make watch cache treat resourceVersion consistent with uncached watch
Fixes#24004
This makes the watch cache handle resourceVersion consistent with an uncached watch API call, and the documented behavior. Watching from resourceVersion=X delivers watch events *after* version X (X is not included):
> // When specified with a watch call, shows changes that occur after that particular version of a resource.
> // Defaults to changes from the beginning of history.
> ResourceVersion string
