This PR is a pretty substantial refactor of the entrypoints of pypiserver (`__main__` and `__init__`) to use the argparse-based config added in #339.
- Updated `RunConfig` and `UpdateConfig` classes to have exclusive init kwargs, instead of taking an namespace. This turned out to be much easier when working with the library-style app initialization in `__init__`, both for direct instantiation and via paste config
- Added an `iter_packages()` method to the `RunConfig` to iterate over packages specified by the configuration (note @elfjes, I think that replacing this with e.g. a `backend` reference will be a nice way to tie in #348)
- Added a general-purpose method to map legacy keyword arguments to the `app()` and `paste_app_factory()` functions to updated forms
- Refactored the `paste_app_factory()` to not mutate the incoming dictionary
- Removed all argument-parsing and config-related code from `__main__` and `core`
- Moved `_logwrite` from `__init__` to `__main__`, since that was the only place it was being used after the updates to `core`
- Updated `digest_file` to use `hashlib.new(algo)` instead of `getattr(hashlib, algo)`, because the former supports more algorithms
- Updated `setup.py` to, instead of calling `eval()` on the entirety of `__init__`, to instead just evaluate the line that defines the version
- Assigned the config to a `._pypiserver_config` attribute on the `Bottle` instance to reduce hacky test workarounds
- Fixed the tox config, which I broke in #339

Adds an argparse config that, while adding subcommands (`pypi-server run` and `pypi-server update`), retains full commandline backwards compatibility with the existing config parsing logic.
There's a bit of hackery required to do this, so this also issues a warning if using the non-subcommand arguments, allowing us to potentially remove support for the old form in our next next major version bump (i.e. 3.0).
Also adds a `.pyproject.toml` with a black config, and a mypy config block to `setup.cfg`.
`mypy` is now called in `tox`, currently only for `config.py`, because nothing else typechecks successfully.
----
* WIP: argparse config
* Complete config
* Test all the config options
* Another test and a note re: being unused
* mypy config, call mypy in tox
* No mypy on pypy
* Fix tox config
* Add venv to black ignore
* fix tox config (again)
* Fix formatting, simplify error handling
* FMT: Run black on changed files
