## Problem We don't have good observability for "stuck" getpage requests. Resolves https://github.com/neondatabase/cloud/issues/23808. ## Summary of changes Log a periodic warning (every 30 seconds) if GetPage request execution is slow to complete, to aid in debugging stuck GetPage requests. This does not cover response flushing (we have separate logging for that), nor reading the request from the socket and batching it (expected to be insignificant and not straightforward to handle with the current protocol). This costs 95 nanoseconds on the happy path when awaiting a `tokio::task::yield_now()`: ``` warn_slow/enabled=false time: [45.716 ns 46.116 ns 46.687 ns] warn_slow/enabled=true time: [141.53 ns 141.83 ns 142.18 ns] ```
