Move almost all project config into pyproject.toml

Remove requirements.txt, requirements-doc.txt, requirements-dev.txt,
and setup.cfg and replace them with equivalent content in
pyproject.toml.

Currently flake8 configuration is missing -- this was configured
in setup.cfg and cannot currently be configured in pyproject.toml
(see PyCQA/flake8#234 ).
