Описание: [mo] Add GC to client-go TLS cache
What metrics, if any, do we want?
Add simple counter metric that shows often the GC has run
Probably needs a feature gate, should it be on by default?
Any concerns with the implementation as it uses runtime.AddCleanup, based on crypto/tls/cache.go
Also replaces global DialerStopCh with a context that is canceled during clean up
[liggitt] original TLS cache addition tried to use Go GC hooks, but it wasn’t reliable back in 2015

Issue
[Marek] Resource size and SLO targets
Can we support 100KB resources? https://github.com/kubernetes/kuberne...
LIST can only fit 2GB Resource size within 30s SLO
Bottlenecks:
1. GZIP Compression
2. Deserialization
3. Network
WatchList for rescue https://github.com/kubernetes/enhance...
But no compression :( https://github.com/kubernetes/kuberne...
