disable timeouts when debugger is active

pytest-dev/pytest-asyncio#216 (comment)
> The PR is not complete until timeout disabling on debugging is
> implemented, as in pytest-timeout.
> Otherwise, any tests debug session ends with TimeoutError quickly.
> I'm not sure is it worth to copy-paste the whole implementation
> from pytest-timeout plugin?
> Maybe adding timeout_setup()/timeout_teardown() hooks for
> implementing them in pytest-asyncio makes the code easier and stablier?
> Should take time for experimenting.
