Klaus Post 2b5e4b853c Improve caching (#19130) ... * Remove lock for cached operations. * Rename "Relax" to `ReturnLastGood`. * Add `CacheError` to allow caching values even on errors. * Add NoWait that will return current value with async fetching if within 2xTTL. * Make benchmark somewhat representative. ``` Before: BenchmarkCache-12 16408370 63.12 ns/op 0 B/op After: BenchmarkCache-12 428282187 2.789 ns/op 0 B/op ``` * Remove `storageRESTClient.scanning`. Nonsensical - RPC clients will not have any idea about scanning. * Always fetch remote diskinfo metrics and cache them. Seems most calls are requesting metrics. * Do async fetching of usage caches.		2024-02-26 10:49:19 -08:00
