Fix bugs in ReservationOpResourceAllocator (introduced by #43171) * We treat a map op and its following non-map ops as the same group. `update_resources` already handles this properly . But `_should_unblock_streaming_output_backpressure` and ` _op_outputs_reserved_remaining` didn't consider this. * Since we don't reserve any resources for `limit` and `streaming_split`, should set `num_cpus=0` for their tasks. * `_reserved_for_op_outputs` currently also includes op's internal output buffers. This is incorrect, because when `preserve_order=True`, task outputs will accumulate in op's internal output buffer, and use all the memory budget from `_reserved_for_op_outputs`. Then we still don't have memory budget to pull the blocks from the internal output buffer. Excluding the internal output buffer from `_reserved_for_op_outputs` fixes this issue. Also deflake `test_backpressure_from_output` and `test_e2e_autoscaling_up`, as they depend on physical memory size of the node. Signed-off-by: Hao Chen <chenh1024@gmail.com>

there is a perf regression for those 2 small-sized test cases in ray-data-resnet50-ingest-file-size-benchmark, due to the new backpressure change (#43171). Update some configs to fix the perf issue. Signed-off-by: Hao Chen <chenh1024@gmail.com>

…on not enabled (#43686) #43171 increased the default memory limit fraction to 50%. because with memory reservation, we have more precise control over the memory. This PR set the default back to 25%, when memory reservation is not enabled, to prevent regression. Signed-off-by: Hao Chen <chenh1024@gmail.com>

Why are these changes needed?
This PR enables per-op resource reservation by default. See docstring of
ReservationOpResourceAllocatorfor the concrete protocol.Besides, this PR also:
OpResourceLimitertoOpResourceAllocator, and adds 2 new APIs.ReservationOpResourceAllocator.StreamingOutputBackpressurePolicy. as this feature is now implemented asReservationOpResourceAllocator.max_task_output_bytes_to_read.use_runtime_metrics_scheduling.ExecutionResources.Related issue number
Closes #42217
