* De-share the Handler struct in core API
An upcoming PR adds a handler that only applies on one of these paths.
Having fields that don't work seems bad.
This never should have been shared. Lifecycle hooks are like a "write"
while probes are more like a "read". HTTPGet and TCPSocket don't really
make sense as lifecycle hooks (but I can't take that back). When we add
gRPC, it is EXPLICITLY a health check (defined by gRPC) not an arbitrary
RPC - so a probe makes sense but a hook does not.
In the future I can also see adding lifecycle hooks that don't make
sense as probes. E.g. 'sleep' is a common lifecycle request. The only
option is `exec`, which requires having a sleep binary in your image.
* Run update scripts
Fix the godoc for RollingUpdateDaemonSet to state that
spec.updateStrategy.rollingUpdate.maxUnavailable is rounded up.
A recent commit changed the godoc to say that the value of this field
was rounded down, but the actual implementation rounds up and always has
rounded up. (This is in contrast to Deployments, where
spec.strategy.rollingUpdate.maxUnavailable is rounded down.)
Follow-up to commit 5aa53f885c.

Change "rounding down" to "rounding up".
When the StatefulSetMinReadySeconds feature gate is disabled,
the registry and validation must properly handle dropping the
minReadySeconds and AvailableReplicas fields
The minReadySeconds field on StatefulSet specifies the minimum
number of seconds for which a newly created Pod should be
ready without any of its containers crashing, for it to
be considered available. The AvailableReplicas field
in the status reflects the replicas that are available
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.
The MaxSurge field on DaemonSet rolling updates allows a daemonset
workload to have two pods running simultaneously on a node during
an update in order to perform zero-disruption handoffs of client
traffic.

Add a new conversion path to replace GenericConversionFunc
reflect.Call is very expensive. We currently use a switch block as part of AddGenericConversionFunc to avoid the bulk of top level a->b conversion for our primary types which is hand-written. Instead of having these be handwritten, we should generate them.
The pattern for generating them looks like:
```
scheme.AddConversionFunc(&v1.Type{}, &internal.Type{}, func(a, b interface{}, scope conversion.Scope) error {
return Convert_v1_Type_to_internal_Type(a.(*v1.Type), b.(*internal.Type), scope)
})
```
which matches AddDefaultObjectFunc (which proved out the approach last year). The
conversion machinery should then do a simple map lookup based on the incoming types and invoke the function. Like defaulting, it's up to the caller to match the types to arguments, which we do by generating this code. This bypasses reflect.Call and in the future allows Golang mid-stack inlining to optimize this code.
As part of this change I strengthened registration of custom functions to be generated instead of hand registered, and also strengthened error checking of the generator when it sees a manual conversion to error out. Since custom functions are automatically used by the generator, we don't really have a case for not registering the functions.
Once this is fully tested out, we can remove the reflection based path and the old registration methods, and all conversion will work from point to point methods (whether generated or custom).
Much of the need for the reflection path has been removed by changes to generation (to omit fields) and changes to Go (to make assigning equivalent structs easy).
