healthz, readyz, and livez are canonical names for checks that the kubelet does. By default, allow access to them in the options. Callers can adjust the defaults if they have a reason to require checks.
system:masters has full power, so the authorization check is unnecessary and just uses an extra call for in-cluster access. Callers can adjust the defaults if they have a reason to require checks.
We're currently only using this for changelog approvals and those should
really be handled by relnotes + RelEng.

the sig-network e2e tests related to services has more than 3k lines.
Some of those e2e tests are related to loadbalancers, that are
cloud provider specific and have special requirements.
We split up the services file and keeps the loadbalancers e2e tests
in their own file and with their own tag, so it is easier to skip
for people that don't run e2e tests in cloud providers.
This commit replaces the CSIMigrationXXXComplete flag
with InTreePluginXXUnregister flag. This new flag will
be a superset of the CSIMigrationXXXComplete. But this
decouple the plugin unregister from CSI migration. So
if a K8s distribution want to go directly with CSI and
do not support in-tree, they can use this flag directly.
Testing:
1. Enable the InTreePluginXXUnregister and not CSIMigrationXXX,
verify that the PVC using old plugin name will have error
saying cannot find the plugin
2. Enable both the InTreePluginXXUnregister and CSIMigrationXXX
verify that the PVC using old plugin name will start to use
the migrated CSI plugin
`debuggingRoundTripper` is a useful throbleshooting tool to debug of Kubernetes API requests and their timing.
Unfortunately, as of today, it can only be used via the `DebugWrappers` function, which automatically adjust the amount of debug information exposed by the roundTripper based on the configured `klog` verbosity.
While `DebugWrappers` definitely fits the purpose for clients using `klog`, this is currently hard to be used for controllers using `controller-runtime`, which uses `github.com/go-logr/logr` for logging.
In this PR we change the visibility of `newDebuggingRoundTripper` and `debugLevel` in order to be directly accessible from users of the `k8s.io/client-go/transport` package.
In particular, the changes proposed in this PR allow users of `controller-runtime` to use the `debuggingRoundTripper` to intercept Kubernetes API requests as follows
```go
import (
ctrl "sigs.k8s.io/controller-runtime"
)
func init() {
ctrl.SetLogger(zap.New())
}
func main() {
// wrap the http transport used by the Kubernetes client
restConfig, err := ctrl.GetConfig()
checkError(setupLog, err, "unable to get kubernetes client config")
restConfig.Wrap(func(rt http.RoundTripper) http.RoundTripper {
return transport.NewDebuggingRoundTripper(rt, transport.DebugJustURL)
})
...
}
```
