Current behavior

I would like to be able to trigger the OnModuleDestroy function for test modules created in my tests. However, this is not possible, the only method exposed is the init() function, which successfully recursively triggers the OnModuleInit function.

  beforeEach(async () => {
    module = await Test.createTestingModule(config).compile();
    await module.init();
  });

Expected behavior

There should be a module.close() function similar to the module.init() function, which then recursively triggers the OnModuleDestroy function for the module and all of its providers.

  afterEach(async () => {
    await module.destroy();
  });

I noticed that a similar function already exists in nest-application.ts. It should work like that.

What is the motivation / use case for changing the behavior?

I use the OnModuleInit and OnModuleDestroy to configure certain modules. I would like to be able to clean up a module after testing, as currently some tests stay stuck after completion. This is because the destroy hook isn't being called.
