This uses the generic ptr.To in k8s.io/utils to replace functions and
code constructs which only serve to return pointers to intstr
values. Other uses of the deprecated pointer package are updated in
modified files.

PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.
The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.
Code that uses the struct definitions needs to be updated.
This was making my eyes bleed as I read over code.
I used the following in vim. I made them up on the fly, but they seemed
to pass manual inspection.
:g/},\n\s*{$/s//}, {/
:w
:g/{$\n\s*{$/s//{{/
:w
:g/^\(\s*\)},\n\1},$/s//}},/
:w
:g/^\(\s*\)},$\n\1}$/s//}}/
:w
This touches cases where FromInt() is used on numeric constants, or
values which are already int32s, or int variables which are defined
close by and can be changed to int32s with little impact.

A recent commit changed name validation from DNS Subdomain to DNS Label.
The assumption was that a subdomain-named SS could never work and the
only reasonable thing to do would be to delete it. But if there is a
finalizer, the delete is not possible because we would reject the update
because the old name (subdomain) did not pass the new validation.
This commit does not re-validate the ObjectMeta on update. Probably
every resource should follow this pattern, but mostly it's a non-issue
becauase the above change (name validation) is not something we do -
this case was excpetional.
Any StatefuleSet which took advantage of this (by having dots in the
name) can't have worked because we set `pod.spec.hostname` from it,
which is validated as a DNS label.
So while this is strictly a breaking change, it doesn't break anything
that was not already broken.
* restructure tests
restructure TestValidateStatefulSet and TestValidateStatefulSetUpdate to be an array and accept list of expected errors. in this commits, no tests were changed and expected errors are not filled yet
* add expected errors
adding expected errors and making the tests pass, without making any changes to the tests
* clean up TestValidateStatefulSet error cases
* clean up TestValidateStatefulSetUpdate cases
* validate new statefulset as part of update validation
* address PR comments
When the StatefulSetMinReadySeconds feature gate is disabled,
the registry and validation must properly handle dropping the
minReadySeconds and AvailableReplicas fields
When the maxsurge daemonset gate is disabled, the registry and validation
must properly handle stripping the field. In the special case where that
would leave the MaxUnavailable field set to 0, we must set it to 1 which
is the default value.
