[Migrated] Zappa requires "future" package under Python 3.x

[jneves]

Originally from: Miserlou/Zappa#1966 by rudyryk

Trying to minify uploaded installation ZIP. Noticed that future package is more than 1.5Mb size, this is far larger than many. But it should not be necessary under Python 3.

Expected Behavior

Don't install and don't require "future" package for Python 3.

Actual Behavior

Zappa CLI can't ZIP package without "future" installed.

Steps to Reproduce

1. Initialize Zappa project
2. Uninstall "future" with pip uninstall future
3. Run zappa --help and get error
