With non strict local retention the storage manager will not trigger data eviction immediately when partition is eligible for eviction but will allow local data to use the whole available disk space. Using standard partition movement policy would force raft to deliver all local data over the network which is not necessary and might take long time. Changed the controller backend to always override the learner start offset when non strict retention is enabled and deliver over the network only data that would normally be retained if strict local retention is turned on.
