Add shard_number to PageserverFeedback and parse it on the compute side. When compute receives a new ps_feedback, it calculates min LSNs among feedbacks from all shards, and uses those LSNs for backpressure. Add `test_sharding_backpressure` to verify that backpressure slows down compute to wait for the slowest shard.
