feature request - allow global async initializer

What is the current behavior?

setupFiles and setupTestFrameworkScriptFile, are running before each test (as it say in the docs)
also there is no way to wait for an async initializer

What is the expected behavior?

1. support a setupFile that export a promise.
2. the tests will run only after the promise is resolved
3. the promise will be run only once before any test will run.

I am running all my test with webStorm jest integration, so creating my own script that initialize and then run the test will fall with webStorm integration

This is more for jest than cra I think. See the response here.

The solution in there will make the async initializer to be run for each test.
I need it to be run once, before any tests.

how do you deal with async initializer like db initialisation?
