ref(quotas): Tune quota cache hashmap

[Dav1dde]

Separate PR to have separate revisions for additional performance tests. ahash should just be an upgrade, for blocking our actual workload seems to favor the blocking mode over the default incremental.

Blocking resizes tend to be better in terms of throughput, especially in setups with multiple writers that can perform the resize in parallel. However, they can lead to latency spikes for insert operations that have to resize large tables.

Latency spikes on inserts are acceptable and we do have a lot of writers.
