Only use endpoint slices to generate network endpoints #1973
Conversation
* remove Endpoints code path and only use EndpointSlices for endpoint decisions * removes --enable-endpoints-slices flag and makes that code path default and only option
The neg syncer was doing some wrong assumptions: 1. Endpoints that are not Ready can have Pods with deletionTimestamp not nil. The Endpoint and EndpointSlice controller will remove the Pod from the corresponding object once it gets deleted (DeletionTimestamp != nil) 2. Any pod with deletionTimestamp == nil is valid, this is the most dangerous assumption, since a pod can be Unready and be used.
* terminating pods are already removed from the endpoints from the EPS, so this check is no longer needed. * this check was a remanent of using endpoints as the source of truth since endpoints did not have a terminating field

Do we not use this flag anymore? Usually when retiring flags, you keep the command line param, but make it log so existing callers on the executable aren't broken. Then fix all of the callers and then delete the flag. If we can fix all of the associated call sites, then ok, we can delete this in one shot.

We will be able to fix the call sites, so this is safe to delete.
