[server][client] Add cooperative KV backpressure based on RocksDB L0

Introduce a two-tier backpressure model to keep RocksDB write stall
from blocking RPC handler threads:

- Tier 1 (piggyback): server reports a normalized [0, 1) pressure on
  PbPutKvRespForBucket once L0 reaches kv.backpressure.l0-slowdown-trigger
  (default 12); client throttles per bucket with max_throttle_ms * p^3
  via client.writer.kv-backpressure.max-throttle-ms (default 5000ms).
- Tier 2 (hard rejection): once L0 reaches RocksDB's
  level0_slowdown_writes_trigger, server throws
  StorageBackpressureException (Errors code 71, RetriableException);
  client applies the same max-throttle window as backoff before retry.

Add maintenance configuration doc for the new server option.
