Formatter does not treat destructured imports

[bpasero]

Imagine an import like this:

import { IWorkbenchEditorService }  from 'vs/workbench/services/editor/common/editorService';

Format, I would love if it ends up to be

import {IWorkbenchEditorService}  from 'vs/workbench/services/editor/common/editorService';

Or whatever you guys think should be the formatting of destructured imports.

I have seen users have strong opinions on weather this should have spaces or not. so looks like this can be a new option.

Unmerged #4609 will format the code but with spaces. A new option for this will be good but maybe after #4757.
