/**
 * Circuit breaker pattern implementation for SMB operations.
 * Prevents cascading failures by temporarily blocking requests to a failing service.
 *
 * The circuit breaker has three states:
 * - CLOSED: Normal operation, requests pass through
 * - OPEN: Service is failing, requests are blocked
 * - HALF_OPEN: Testing if service has recovered

## Changelog since v1.15.11

## Changes by Kind

### Bug or Regression

- Client-go: resolves an issue with informers falling back to full list requests when timeouts are encountered, rather than re-establishing a watch. ([#89978](https://github.com/kubernetes/kubernetes/pull/89978), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

- Fix a concurrent map writes error in kubelet ([#93773](https://github.com/kubernetes/kubernetes/pull/93773), [@knight42](https://github.com/knight42)) [SIG Node]
- Fix calling AttachDisk on a previously attached EBS volume ([#93567](https://github.com/kubernetes/kubernetes/pull/93567), [@gnufied](https://github.com/gnufied)) [SIG Cloud Provider, Storage and Testing]

   * com.google.common.testing.junit3.TearDownTestCase} and {@code
   * com.google.common.testing.junit4.TearDownTestCase} for example.
   *
   * <p>A failing {@link TearDown} may or may not fail a tl4j test, depending on the version of
   * JUnit test case you are running under. To avoid failing in the face of an exception regardless
   * of JUnit version, implement a {@link SloppyTearDown} instead.
   *

      log.put("failing task running")
      throw RuntimeException("boom!")
    }

    queue.schedule("task", TimeUnit.MILLISECONDS.toNanos(200)) {
      log.put("normal task running")
      return@schedule -1L
    }

    queue.idleLatch().await(500, TimeUnit.MILLISECONDS)

    assertThat(log.take()).isEqualTo("failing task running")

* Stateful Apps:
  * **alpha** PetSets manage stateful apps
  * **alpha** Init containers provide one-time setup for stateful containers
* Updating:
  * Retry Pod/RC updates in kubectl rolling-update.
  * Stop 'kubectl drain' deleting pods with local storage.
  * Add `kubectl rollout status`
* Security/Auth
  * L7 LB controller and disk attach controllers run on master, so nodes do not need those privileges.
