[issue27376] Add mock_import method to mock module

[Israel Fruchter]

Israel Fruchter added the comment:

Some real use cases is needed, like testing a code that behave differently on case of package availability.

I think something like patch for modules can be useful here, so you could have some control on what would be returned.
