This updates the StaleSlices() method in EndpointSliceTracker to also
ensure that the tracker does not have more slices than have been
provided.

Add support to the endpoint slice mirroring controller to mirror
annotations, in addition to labels, but don´t mirror endpoint
triggertime annotation.
Also, fix a bug in the endpointslice mirroring controller, that
wasn't updating the mirrored slice with the new labels, in case
that only the endpoint labels were modified.
Previously the controllers would proceed with additional creates,
updates, or deletes if 1 failed. That could potentially result in
scenarios where an EndpointSlice create or update failing while a delete
worked. This updates the logic so that removals will not happen if
additions fail.
The KEP specifies that the controller will "mirror all labels from the
Endpoints resource and all endpoints and ports from the corresponding subset".
I'd missed that in my initial implementation, this should fix that.
This mirrors an earlier fix to the EndpointSlice controller. I'll make a
follow up PR to move this component to a shared package, but that seems
beyond the scope of a bug fix PR.
