Remove Duplicated Dependencies and PEP 517 Support (#2173)

* Remove duplicated dependencies

* Specify setuptools as the tool for generating distribution (PEP 517)

* Add `isort` to `dev_require`

* manage all dependencies in setup.py

* Execute `make pretty`

* Set usedevelop to true (revert previous change)
