Problem
Some code actions, such as extract method, may be used very often. This currently requires too many steps:

1. Highlight expression to be extracted
2. Use editor.action.quickFix shortcut
3. Select Extract method from list of quick fixes and press enter.

Desired Flow
User creates a keybinding:

{
    "key": "cmd+r,m",
    "command": "editor.action.applyQuickFix",
    "arguments": ["extract"]
}

1. Highlight expression to be extracted
2. Press ctrl+r, m

Complications

1. Multiple extract method options may exist. In this case, I think we'd want to display a list of all possible extract code actions

2. Ideally the same shortcuts should work across languages
