This change adds the generic ability for request handlers that run
before WithAudit to set annotations in the audit.Event.Annotations
map.
Note that this change does not use this capability yet. Determining
which handlers should set audit annotations and what keys and values
should be used requires further discussion (this data will become
part of our public API).

This change removes support for basic authn in v1.19 via the
--basic-auth-file flag. This functionality was deprecated in v1.16
in response to ATR-K8S-002: Non-constant time password comparison.
Similar functionality is available via the --token-auth-file flag
for development purposes.

So multiple instances of kube-apiserver can bind on the same address and
port, to provide seamless upgrades.

Currently, /readyz starts reporting failure after ShutdownDelayDuration
elapses. We expect /readyz to start returning failure as soon as
shutdown is initiated. This gives the load balancer a window defined by
ShutdownDelayDuration to detect that /readyz is red and stop sending
traffic to this server.

The old flag name doesn't make sense with the renamed API Priority and
Fairness feature, and it's still safe to change the flag since it hasn't done
anything useful in a released k8s version yet.

- Add handlers for service account issuer metadata.
- Add option to manually override JWKS URI.
- Add unit and integration tests.
- Add a separate ServiceAccountIssuerDiscovery feature gate.
Additional notes:
- If not explicitly overridden, the JWKS URI will be based on
the API server's external address and port.
- The metadata server is configured with the validating key set rather
than the signing key set. This allows for key rotation because tokens
can still be validated by the keys exposed in the JWKs URL, even if the
signing key has been rotated (note this may still be a short window if
tokens have short lifetimes).
- The trust model of OIDC discovery requires that the relying party
fetch the issuer metadata via HTTPS; the trust of the issuer metadata
comes from the server presenting a TLS certificate with a trust chain
back to the from the relying party's root(s) of trust. For tests, we use
a local issuer (https://kubernetes.default.svc) for the certificate
so that workloads within the cluster can authenticate it when fetching
OIDC metadata. An API server cannot validly claim https://kubernetes.io,
but within the cluster, it is the authority for kubernetes.default.svc,
according to the in-cluster config.

From the listen godoc:
For TCP networks, if the host in the address parameter is empty or a
literal unspecified IP address, Listen listens on all available unicast
and anycast IP addresses of the local system.
Since the BindNetwork options is "tcp" by default, using an unspecified
address doesn't bind the listener to the IP family.

apiserver adds localhost to the alternateDNS field
if the bind address is 0.0.0.0.
This PR considers the IPv6 unspecified address too.

The old name is too broad, we wanted a name that is more specific to
the actual feature.
This is an alpha gate, and no release has yet associated any
functionality with this gate.
