There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change, since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

Aliaksandr Valialkin	29bbab0ec9	lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected ... The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts. Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon, which should return CPU and disk IO usage to normal levels.

This condition may occur after the following sequence of events: 1) A goroutine enters the loop body when len(addRowsConcurrencyCh) == cap(addRowsConcurrencyCh) inside Storage.searchTSIDs. 2) All the goroutines return from Storage.AddRows. 3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body.
