Jack Kleeman 51b8ce994d Dynamic serving certificate
Reload certificate cert and key file from disk every minute and notify
the dynamic certificate controller when they change, allowing serving
tls config to be updated.

Jack Kleeman 40fefa1b37 Plumb dynamic SNI certificates
We create and use a dynamic certificate provider for the SNI serving
certificates. Currently we only use static serving certificate
providers, so the files are not reloaded, but we should be able to move
to a provider that is able to reload later on.

Han Kang 4a680138c0 Fix double counting issue for request metrics on timeout.
Currently we record request metrics during the normal request flow and
we also manually invoke `Record` in the timeout handler to record
timeouts. This means that we effectively double count whenever we
timeout. This PR renames the `Record` function to `RecordRequestError`
to more accurately reflect the intended side-effect of the function
call.

Jack Kleeman 8da4640a3d Plumb dynamic serving certificates
We create and use a dynamic certificate provider for the main apiserver
serving certificates: SNI will be handled separately later. Currently we
only use static serving certificate providers, so the files are not
reloaded, but we should be able to move to a provider that is able to
reload later on.

Monis Khan 298cf1beec Encryption config: correctly handle overlapping providers
This change updates NewPrefixTransformers to not short-circuit on
the first transformer that has a matching prefix.  If the same type
of encryption ProviderConfiguration is used more than once, they
will share the same prefix.  A failure in the first one should not
prevent a later match from being attempted.

Added TestCBCKeyRotationWithOverlappingProviders unit test to
prevent regressions.  Note that this test explicitly exercises this
flow using an EncryptionConfiguration object as the structure of the
resulting transformer is an important part of the check.

Walter Fender da748a626b Add support for konnectivity service to the etcd3 client.
If konnectivity service is enabled, the etcd client will now use it.
This did require moving a few methods to break circular dependencies.

Han Kang 050d1b223c add /livez as a liveness endpoint for kube-apiserver
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

Clayton Coleman 72566fea6c Replace HTTP compression with an inline handler
The previous HTTP compression implementation functioned as a filter, which
required it to deal with a number of special cases that complicated the
implementation.

Instead, when we write an API object to a response, handle only that one
case. This will allow a more limited implementation that does not impact
other code flows.

Also, to prevent excessive CPU use on small objects, compression is
disabled on responses smaller than 128Kb in size.
