This change adds a flag --encryption-provider-config-automatic-reload
which will be used to drive automatic reloading of the encryption
config at runtime. While this flag is set to true, or when KMS v2
plugins are used without KMS v1 plugins, the /healthz endpoints
associated with said plugins are collapsed into a single endpoint at
/healthz/kms-providers - in this state, it is not possible to
configure exclusions for specific KMS providers while including the
remaining ones - ex: using /readyz?exclude=kms-provider-1 to exclude
a particular KMS is not possible. This single healthz check handles
checking all configured KMS providers. When reloading is enabled
but no KMS providers are configured, it is a no-op.
k8s.io/apiserver does not support dynamic addition and removal of
healthz checks at runtime. Reloading will instead have a single
static healthz check and swap the underlying implementation at
runtime when a config change occurs.

This change updates TestAggregatedAPIServer and the related test
server wiring to exercise the full network path between the Kube API
server and the aggregated API server. We now assert that the wardle
API service and Kube API server discovery endpoints are fully healthy.
CRUD operations are performed through the Kube API server to the
wardle API server.

we disabled the /healthz check because our test blocks one post-start
hook from finishing. Instead we should check all the other /healthz/...
endpoints before running the tests
To make sure that the storage version filter can block certain requests until
the storage version updates are completed, and that the apiserver works
properly after the storage version updates are done.
Current calculations assume that -trimpath is not passed to go tool
compile, which is not the case for test binaries built with bazel. This
causes issues for integration tests right now but is generally not
correct.
The approach taken here is a bit of a hack but it works on the
assumption that if and only if trimpath is passed, we are running under
bazel. I didn't see a good spot for pkgPath(), so I just copied it
around.
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
add startup sequence duration and readyz endpoint
add rbac bootstrapping policy for readyz
add integration test around grace period and readyz
rename startup sequence duration flag
copy health checks to fields
rename health-check installed boolean, refactor clock injection logic
cleanup clock injection code
remove todo about poststarthook url registration from healthz
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
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.

apiserver: master count and lease endpoint test
**What this PR does / why we need it**: Adds a test to make sure master count and lease endpoint reconcilers work well together, so we can bump LeaseEndpoint to beta. Based on Jordan's comment https://github.com/kubernetes/kubernetes/pull/58474#issuecomment-369954890.

kube-apiserver: move StartTestServer tests into test/integration/master
Fix the failing scale test
kube-apiserver's TestServer now returns a struct instead of individual values
The DestroyFunc functions returned by generic.NewRawStorage is never
called when we do a StartTestServer() in the test suite. For a quick
hack for now, added TrackStorageCleanup/RegisterStorageCleanup and
CleanupStorage. Note that unless TrackStorageCleanup is called (which
is called only from the test suite) the other two methods are
no-ops essentially. So no change in behavior at runtime. This vastly
brings down the number of goroutines that are left behind when this
test is executed and should reduce if not eliminate the flakiness
of TestCRD
