The registry abstraction is unnecessary and adds direct coupling to the
core types. By using a wrapper, we carry through the default
implementations of the non-mutating operations. The DeleteCollection
method is explicitly patched out since it cannot be correctly
implemented on the storage currently.
As a result, TableConvertor is now exposed.
A few other minor refactorings
* Corrected the case of some variables
* Used functions instead of methods for several helper methods
* Removed the legacy Deleter - service was the only remaining consumer
RangeSize was restricting IPv6 subnets to a /66 due to the
logic using a uint64. This is not practical for IPv6.
This change removes the /64 restriction, but also sets a limit
on the range that can be allocated, so that the bitmap will not grow too large.

Remove ExternalTrafficLocalOnly from kube_feature gate
*What this PR does / why we need it**:
This PR is for v1.10.
External Source IP Preservation (ESIPP) had been promoted to GA since 1.7. Following the proposal on https://github.com/kubernetes/kubernetes/issues/46404#issuecomment-303939180, we should be able to remove it from feature gate now.
Added release note to announce this.
Also ref the previous attempt: https://github.com/kubernetes/kubernetes/pull/45857.

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

Updates RangeSize error message and tests for IPv6.
**What this PR does / why we need it**:
Updates the RangeSize function's error message and tests for IPv6. Converts RangeSize unit test to a table test and tests for success and failure cases. This is needed to support IPv6. Previously, it was unclear whether RangeSize supported IPv6 CIDRs. These updates make IPv6 support explicit.

Currently setting watch cache size for a given resource does not disable
the watch cache. This commit adds a new `default-watch-cache-size` flag
to map to the existing field, and refactors how watch cache sizes are
calculated to bring all of the code into one place. It also adds debug
logging to startup to allow us to verify watch cache enablement in
production.

Support exec/attach/portforward in `kubectl proxy`

Fixes#32026
```release-note
`kubectl proxy` will now correctly handle the `exec`, `attach`, and `portforward` commands. You must pass `--disable-filter` to the command in order to allow these endpoints.

Use helper to init ClusterIP and NodePort in Create of service
**What this PR does / why we need it**:
Make service `Create` more readable and testable.
- use `initClusterIP` introduced in #46197 to init ClusterIP allocation in service `Create`
- add a new helper `initNodePort` to init NodePort allocation in service `Create`
- TBD: add test case for `initNodePort`. This will cover the NodePort allocation process in `Create`. If this PR makes sense, I will write a test case later.

add svc and netpol to discovery
Fixes https://github.com/kubernetes/kubernetes/issues/48962
one shortname was missing entirely, the other was on a storage not actually used as storage.
@ncdc
Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.
All Stores in Kubernetes follow the same logic for determining the name
of an object. This change makes it so that CompleteWithOptions defaults
the ObjectNameFunc if it is not specified. Thus a user does not need to
remember to use ObjectMeta.Name. Using the wrong field as the name can
lead to an object which has a name that bypasses normal object name
validation.

Change an Errorf to a Fatalf to prevent a panic.
In #37982 we see that if this error is hit then we will panic on the next line. Lets use `Fatalf` where appropriate :)
This does *not* fix the flake, since that's caused by the test assuming that a particular port is free.

Don't use global rand for nodeport and IP allocs
Seed it at construction.
The result of this was that an update to a Service would release the
NodePort temporarily (the repair loop would fix it in a minute). During
that window, another Service could get allocated that Port.

Reuse fields and labels
This should significantly reduce memory allocations in apiserver in large cluster.
Explanation:
- every kubelet is refreshing watch every 5-10 minutes (this generally is not causing relist - it just renews watch)
- that means, in 5000-node cluster, we are issuing ~10 watches per second
- since we don't have "watch heartbets", the watch is issued from previously received resourceVersion
- to make some assumption, let's assume pods are evenly spread across pods, and writes for them are evenly spread - that means, that a given kubelet is interested in 1 per 5000 pod changes
- with that assumption, each watch, has to process 2500 (on average) previous watch events
- for each of such even, we are currently computing fields.
This PR is fixing this problem.
This patch adds the option to set a nodeport when creating a NodePort
service. In case of a port allocation error due to a specified port
being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
