If konnectivity service is enabled, the etcd client will now use it.
This did require moving a few methods to break circular dependencies.
Factored in feedback from lavalamp and wenjiaswe.
go fmt
make func private
refactor config_test
Two primary refactorings:
1. config test checkPath method is now each a distinct test
run (which makes it easier to see what is actually failing)
2. TestNewWithDelegate's root path check now parses the json output and
does a comparison against a list of expected paths (no more whitespace
and ordering issues when updating this test, yay).
go fmt
modify and simplify existing integration test for readyz/livez
simplify integration test
set default rbac policy rules for livez
rename a few functions and the entrypoint command line argument (and etcetera)
simplify interface for installing readyz and livez and make auto-register completion a bootstrapped check
untangle some of the nested functions, restructure the code

Disambiguating konnectivity service by renaming it egress selector.
Switched feature flag to KUBE_ENABLE_EGRESS_VIA_KONNECTIVITY_SERVICE
On local networks (such as the typical connection path between
control plane components) gzip compression increases CPU use and
end to end p99 latency rather than decreasing it. Disable compression
within the control plane components like a 1.15 cluster would be
configured.
Since we never use the cobras "SilenceErrors" or "SilenceUsage",
a command executed with "cmd.Execute()" will never return an error
without printing it.
The current behavior results in all error messages being printed twice:
Example:
$ kubectl abc
Error: unknown command "abc" for "kubectl"
Run 'kubectl --help' for usage.
unknown command "abc" for "kubectl"
This applies to all cli commands using Cobra. To verify, follow the code
path of the Execute function:

TestWatchBasedManager was racing with the default namespace creation.
To fix that flake and to ensure integration tests using a shared etcd
don't accidentally overlap in the future, move the three main tests
using the default namespace to separate namespaces, and have
TestWatchBasedManager create that namespace before it runs.
Make StartTestServer wait for default namespace creation, which will
reduce other flakes until future changes completely remove use of default
namespace.
From a failed integration run:
watch_manager_test.go:66: namespaces "default" not found
watch_manager_test.go:66: namespaces "default" not found
watch_manager_test.go:66: namespaces "default" not found
This package contains public/private key utilities copied directly from
client-go/util/cert. All imports were updated.
Future PRs will actually refactor the libraries.
Updates #71004
Moved all flag code from `staging/src/k8s.io/apiserver/pkg/util/[flag|globalflag]` to `component-base/cli/[flag|globalflag]` except for the term function because of unwanted dependencies.
The storage version now is solely decided by the
scheme.PrioritizedVersionsForGroup(). For cohabitating resources, the storage
version will be that of the overriding group as returned by
storageFactory.getStorageGroupResource().
Fixes#71730
0 indicates standby, 1 indicates master, label indicates which lease.
Tweaked name and documentation
Factored in Mike Danese feedback.
Removed dependency on prometheus from client-go using adapter.
Centralized adapter import.
Fixed godeps
Fixed boilerplate.
Put in fixes for caesarxuchao
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Fixes lint errors in kubeapiserver/admission, kubeapiserver/authorizer,
kubeapiserver/authenticator. Also enables lint testing of these
directories.
Fixed go format.
Fixed changes from config.
The service account authenticator isn't the only authenticator that
should respect API audience. The authentication config structure should
reflect that.
Individual implementations are not yet being moved.
Fixed all dependencies which call the interface.
Fixed golint exceptions to reflect the move.
Added project info as per @dims and
https://github.com/kubernetes/kubernetes-template-project.
Added dims to the security contacts.
Fixed minor issues.
Added missing template files.
Copied ControllerClientBuilder interface to cp.
This allows us to break the only dependency on K8s/K8s.
Added TODO to ControllerClientBuilder.
Fixed GoDeps.

Synchronous & unbatched audit log writes
**What this PR does / why we need it**:
When enabling buffered audit log file writes to reduce latency under high load, we shouldn't be batching the writes, as the large data write can have an inverse (though unpredictable) impact. Additionally, batched audit log writes should not be done asynchronously, as this just creates lock contention on the log writer.

Refactor storage factory config with Complete().New() flow
**What this PR does / why we need it**:
1. Split `BuildStorageFactory` constructor into `Complete().New()` flow to build an instance for etcd storage.
2. Put `EtcdOptions` and `StorageSerializationOptions` into a `StorageFactoryOptions` for a more reasonable structured config object.

apiserver: make loopback logic in SecureServingOptions reusable
For reuse in other components this PR separates the loopback logic from the GenericApiServer config.
Before this the advertised IP (which shows up in the server cert) in case of
listening to loopback was the first host interface IP. This makes self-signed
certs non-constant, such that we cannot use fixtures.
