Enforce "Import Destructuring Spacing" in tslint

[kirjs]

Motivation

Right now there is no consistent way to handle spaces in destructured imports, this introduces some noise in commits as right now we have no spaces, but angular CLI as well as some formatters actually add spaces.

Also ts-lint only validates the case with spaces

Solution

• Add spaces across the codebase
• Add TS-lint rule
• Document the configuration for the websorm and VSCode

Editor configuration

Intellij/Webstorm
Settings -> Code Style -> TypeScript -> Spaces Tab -> Check “ES6 import/export braces”
