Allows usage such as the following...

from uvicorn import Config, Server

# Do some custom event loop setup here
...

# Run the server
config = Config(app=..., loop="none")  # Alternates are "auto", "asyncio", "uvloop", "iocp"
server = Server(config=config)
server.run()  # Or `await server.serve()` if we're already in an async context.

* Add changes from PR #992

This commit will bring in changes to uvicorn/config.py added by @Kludex
in PR #992, updating for the latest master branch.

* Correct SSL type annotations

#992
https://docs.python.org/3/library/ssl.html#ssl.SSLContext.load_cert_chain

- `certfile` is a required positional argument when running
  `SSLContext.load_cert_chain`, so annotating as `Optional` (which
  allows `None`) would not be ideal. Path-like objects are acceptable,
  so after `from pathlib import Path`, the annotation is
  `certfile: Union[Path, str]`.
- `if self.is_ssl and self.ssl_certfile` will help ensure that the
  `self.ssl_certfile` required positional argument is present.

* Simplify log_config type annotation

`Dict[str, Any]` can be simplified to `dict`.

* Add type annotation for app

#990
#992

app is sometimes a string, as described in uvicorn/main.py. In other
cases, especially in the tests, app is an ASGI application callable.

This commit will add a type annotation for the app argument to address
these use cases.

* Simplify if expression in Config().headers

* Allow paths to be used for Config(env_file)

* Add asyncio Protocol types to class Config kwargs

Protocol classes are sometimes used for the app kwarg, such as in
tests/test_config.py.

* Improve use of Literal type for ASGI interfaces

https://mypy.readthedocs.io/en/stable/literal_types.html

This commit will retain the use of literals to define ASGI protocol
versions, but improve and correct the use of literal types.

As described in the mypy docs, `Literal["2.0", "3.0"]` is a simpler way
to write `Union[Literal["2.0"], Literal["3.0"]]`.

* Add type annotation to Config kwargs in workers.py

https://mypy.readthedocs.io/en/stable/type_inference_and_annotations.html

This is just one of those times when mypy needs a little help.

* Add type annotations to test_config.py

PR #978 added logic to convert `reload_dirs` from string to list, as
shown in `test_reload_dir_is_set()`, so the annotation on reload_dirs
will be updated to accept a string.

* Type-annotate constants in uvicorn/config.py

Prevents mypy `[has-type]` errors ("Cannot determine type of {object}")

* Correct type annotations in uvicorn/importer.py

#1046
#1067

The relationship between module imports and calls in uvicorn/config.py
was previously unclear. `import_from_string` was annotated as returning
a `ModuleType`, but was being used as if it were returning callables.
Mypy was raising "module not callable" errors, as reported in #1046.

Current use cases of `import_from_string` include:

- `uvicorn.Config.HTTP_PROTOCOLS`, `uvicorn.Config.WS_PROTOCOLS`:
  `Type[asyncio.Protocol]` (these are subclasses of asyncio protocols,
  so they are annotated with `Type[Class]` as explained in the mypy docs
- `uvicorn.Config.LOOP_SETUPS`: `Callable` (each loop is a function)
- `uvicorn.Config().loaded_app`: `ASGIApplication` (should be an ASGI
  application instance, like `Starlette()` or `FastAPI()`)

Ideally, the return type of `import_from_string` would reflect these use
cases, but the complex typing will be difficult to maintain. For easier
maintenance, the return type will be `Any`, and objects returned by
`import_from_string` will be annotated directly.

* Use os.PathLike for paths in uvicorn/config.py

#1067 (comment)

Alternative to `pathlib.Path` introduced in Python 3.6.

* Use more specific types in test_config.py

https://docs.pytest.org/en/latest/reference/reference.html#pytest.FixtureRequest

- Add custom types for exceptions and start response
- Use `MutableMapping` for `os.environ`: matches starlette/config.py.
- Use `pytest.FixtureRequest` for fixture requests. The `param`
  attribute is optional, so mypy requires a check for the attribute
  before indexing into it (`getattr(request, "param")`).

#1067 (comment)

it is currently, `is_ssl` could return `True` without `certfile`.
