Roman Khachatryan updated FLINK-23137:
--------------------------------------
Description:
TM should own changelog backend state to prevent re-uploading state on
checkpoint abortion (or missing confirmation). A simpler solution to only own
aborted state is less maintanable in the long run.
For that, on JM side, ChangelogStateBackendHandle shouldn't discard and nor
register and yhared state.
Ticket for TM-side: FLINK-23139
See [state ownership design
