Can pathlib be used for pkg_resources

[thechief389]

In Python version 3.4 and higher, there's a new pathlib module that does things similar to how pkg_resources does it.

This could be a good approach to dropping versions 2 and lower. I could've made a pull request instead, but I made this issue in case someone had any opinions about this.

With Python 2.7 EOL set to 2020, there's currently no plan to drop support for it.

I've created #1458 to capture the effort to drop support for Python 2.7.

We might consider revisiting this issue in the future once Python 2.7 is no longer supported (on the latest master branch).
