refactor(best practices): Update rules for Prettier integration

BREAKING CHANGE: Requires min eslint version of 4.x.

BREAKING CHANGE: Multiple rules disabled and handled by Prettier, this will change code style for defaults based projects.

Upgrade: After upgrading with defaults, any editor Prettier plugin can be used to update style. The pre-commit hook will also fix & write the prettier changes.
