nest: TestingModuleBuilder is missing overrideModule

Feature Request

Is your feature request related to a problem? Please describe.

I want to use mock modules to override functionalities of the module instead of overriding internals of the module again and again.

Describe the solution you’d like

A overrideModule method similar to overrideProvider would solve the issue, example:

Test.createTestingModule({
  ...
})
  .overrideModule(LoggerModule)
  .useClass(LoggerTestingModule)
  .compile();

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

For the cases of e2e / integration testing in a project with many encapsulated libraries / modules it would be very helpful to be able to override entire modules instead of overriding internals of the modules every time the module is part of a testing module.
