Remove hacks from ScheduledJobs cron spec parsing
Previusly `github.com/robfig/cron` library did not allow passing cron spec without seconds. First commit updates the library, which has additional method ParseStandard which follows the standard cron spec, iow. minute, hour, day of month, month, day of week.
@janetkuo @erictune as promised in #30227 I've updated the library and now I'm updating it in k8s

Centralize install code
Trying to figure out a way to do this that makes the changes as painless to roll out as possible. This is going to be a multi-step process...

Simplify canonical element term in deepcopy
Replace the old functional canonical element term in deepcopy registration with direct struct instantiation.
The old way was an artifact of non-uniform pointer/non-pointer types in the signature of deepcopy function. Since we changed that to always be a pointer, we can simplify the code.

There's been enough people broken by not committing generated code, that we
should undo that until we have a proper client that is `go get` compatible.
This is temporary.
This mostly takes the previously checked in files and removes them, and moves
the generation to be on-demand instead of manual. Manually verified no change
in generated output.
This drives conversion generation from file tags like:
// +conversion-gen=k8s.io/my/internal/version
.. rather than hardcoded lists of packages.
The only net change in generated code can be explained as correct. Previously
it didn't know that conversion was available.
This is the last piece of Clayton's #26179 to be implemented with file tags.
All diffs are accounted for. Followup will use this to streamline some
packages.
Also add some V(5) debugging - it was helpful in diagnosing various issues, it
may be helpful again.
This drives most of the logic of deep-copy generation from tags like:
// +deepcopy-gen=package
..rather than hardcoded lists of packages. This will make it possible to
subsequently generate code ONLY for packages that need it *right now*, rather
than all of them always.
Also remove pkgs that really do not need deep-copies (no symbols used
anywhere).
In bringing back Clayton's PR piece-by-piece this was almost as easy to
implement as his version, and is much more like what I think we should be
doing.
Specifically, any time which defines a .DeepCopy() method will have that method
called preferentially. Otherwise we generate our own functions for
deep-copying. This affected exactly one type - resource.Quantity. In applying
this heuristic, several places in the generated code were simplified.
To achieve this I had to convert types.Type.Methods from a slice to a map,
which seems correct anyway (to do by-name lookups).
Make unversioned.ListMeta implement List. Update all the *List types so they implement GetListMeta.
This helps avoid using reflection to get list information.
Remove all unnecessary boilerplate, move the interfaces to the right
places, and add a test that verifies that objects implement one, the
other, but never both.
Having internal and external integer types being different hides
potential conversion problems. Propagate that out further (which will
also allow us to better optimize conversion).

Make all defaulters public
Will allow for generating direct accessors in conversion code instead of using reflection.

Added selector generation to Job's
strategy.Validate, right before validation.
Can't do in defaulting since UID is not known.
Added a validation to Job to ensure that the generated
labels and selector are correct when generation was requested.
This happens right after generation, but validation is in a better
place to return an error.
Adds "manualSelector" field to batch/v1 Job to control selector generation.
Adds same field to extensions/__internal. Conversion between those two
is automatic.
Adds "autoSelector" field to extensions/v1beta1 Job. Used for storing batch/v1 Jobs
- Default for v1 is to do generation.
- Default for v1beta1 is to not do it.
- In both cases, unset == false == do the default thing.
Release notes:
Added batch/v1 group, which contains just Job, and which is the next
version of extensions/v1beta1 Job.
The changes from the previous version are:
- Users no longer need to ensure labels on their pod template are unique to the enclosing
job (but may add labels as needed for categorization).
- In v1beta1, job.spec.selector was defaulted from pod labels, with the user responsible for uniqueness.
In v1, a unique label is generated and added to the pod template, and used as the selector (other
labels added by user stay on pod template, but need not be used by selector).
- a new field called "manualSelector" field exists to control whether the new behavior is used,
versus a more error-prone but more flexible "manual" (not generated) seletor. Most users
will not need to use this field and should leave it unset.
Users who are creating extensions.Job go objects and then posting them using the go client
will see a change in the default behavior. They need to either stop providing a selector (relying on
selector generation) or else specify "spec.manualSelector" until they are ready to do the former.
This is needed for Job because it uses PodSpec and PodSpec
does not have auto-generatable conversion for some reason.
Copied pkg/apis/extensions/v1beta1/conversion.go, and removed
non-Job things.
