Kubernetes Submit Queue d19a2841e3 Merge pull request #47645 from jsafrane/integration-test-speedup

Automatic merge from submit-queue (batch tested with PRs 48139, 48042, 47645, 48054, 48003)

Speed up attach/detach controller integration tests

Internal attach/detach controller timers should be configurable and tests should use much shorter values.

`reconcilerSyncDuration` is deliberately left out of `TimerConfig` because it's the only one that's not a constant one, it's configurable by user.

Fixes #47129

PV controller tests are the slowest ones now.
