apiserver: Update genericapiserver to panic on listener error
Previously runServer would try to listen again if a listener error occurred. This commit changes the response to a panic to allow a process manager (systemd/kubelet/etc) to react to the failure.
**Release note**:
```release-note
The Kubernetes API server now exits if it encounters a networking failure (e.g. the networking interface hosting its address goes away) to allow a process manager (systemd/kubelet/etc) to react to the problem. Previously the server would log the failure and try again to bind to its configured address:port.

e2e: Prefer kubeconfig host to default
Previously it was necessary to pass ``-host`` to ``e2e.test`` even if ``-kubeconfig`` was specified since otherwise a localhost default would be used. This change ensures that the default is only used when kubeconfig is not set.

On any cloud (GCE or AWS), a lag between creating the LoadBalancer and
having it actually start serving traffic is expected. On AWS the lag is
larger, and we weren't correctly using the longer wait on our first
request.
Use a longer wait period on our first request.

Retry in get-kube.sh to avoid download flakes.
GCS has up to 2% 5xx rates, so retrying is critical.
This is currently failing about 8 times per day [according to the dashboard](https://storage.googleapis.com/k8s-gubernator/triage/index.html?test=Extract#be2f33fb1e6dd2389d12). It could be backported to reduce the flake rate.

Reading directly from a hijacked connection isn't safe because some
data may have already been read by the server before Hijack was called.
To ensure all data will be received it's safer to read from the returned
bufio.Reader.

The Job Listers still use selectors, because this is the
behavior expected by callers. This clarifies the meaning of the
returned list. Some callers may need to switch to using
GetControllerOf() instead, but that is a separate, case-by-case issue.
