Moving towards a whitelist approach for MANIFEST.in

[craig-rueda]

There's a lot of stuff in assets that doesn't need to be shipped and/or served with Superset. The current setup of MANIFEST.in starts out by doing an initial recursive-include against static and then selectively excludes several items. As a result, several files are being left behind, such as terser caches, .rc files, package.json, etc.

Fixes #8107

I think this line needs to be changed to use version_info.json:
https://github.com/apache/incubator-superset/blob/master/setup.py#L30

Running pip install <superset-sdist-tarball> is failing for me because there is no package.json in the dist
