We use space-before-function-paren in our eslint rules for readability. I'd like an option to format to this behavior

• VSCode Version: 1.7.1
• OS Version: macOS Sierra 10.12.1

Steps to Reproduce:

1. Type function foo () { }
2. Format the code (if it doesn't auto-format)
3. Code is formatted to function foo() { } with no mechanism to override
