[Feature]: Add config option "worker(Max)Retries" instead of hardcoded maxRetries: 3 in jest-runner 🙂

[andry-brill]

🚀 Feature Proposal

Could it be possible to add this._globalConfig.worker(Max)Retries to configure maxRetries instead of hardcoded 3 ? 🙂

test-runner/src/index.ts

    const worker = new Worker(require.resolve('./testWorker'), {
      enableWorkerThreads: this._globalConfig.workerThreads,
      exposedMethods: ['worker'],
      forkOptions: {serialization: 'json', stdio: 'pipe'},
      // The workerIdleMemoryLimit should've been converted to a number during
      // the normalization phase.
      idleMemoryLimit:
        typeof this._globalConfig.workerIdleMemoryLimit === 'number'
          ? this._globalConfig.workerIdleMemoryLimit
          : undefined,
      maxRetries: 3,
      numWorkers: this._globalConfig.maxWorkers,
      setupArgs: [{serializableResolvers: [...resolvers.values()]}],
    }) as JestWorkerFarm<TestWorker>;

Motivation

Why we can configure maxWorkers option but not maxRetries? 🧐

Example

I would love to have this value = 0 in my jest tests. 🙏🏻
As message Jest worker encountered 4 child process exceptions, exceeding retry limit not helping at all (usually).

Pitch

It's improvement to existing code (jest-runner).
