Class fields should be configurable:true

[loganfsmyth]

Spec updated: tc39/proposal-class-fields#35

It defaults to false in Babel here: https://github.com/babel/babel/blob/7.0/packages/babel-plugin-transform-class-properties/src/index.js#L28 We should add configurable: true to that config.

    Object.defineProperty(REF, KEY, {
      // configurable is false by default
      enumerable: true,
      writable: true,
      value: VALUE
    });

We'd ask that if you've already made a PR you'd let someone new take this 😄 , thanks!

• Comment below you are going to do this (for others to know)
• Read CONTRIBUTING.md
• Check you are on 7.0 branch with git checkout 7.0 and then make a branch off of that to PR
• Join our slack if you haven't already if you need more immediate help or just comment in this issue/PR (this might be down, we can add you manually)
• check the class properties package/folder: https://github.com/babel/babel/tree/7.0/packages/babel-plugin-transform-class-properties
• follow the steps above in changing the behavior
• fix tests https://github.com/babel/babel/tree/7.0/packages/babel-plugin-transform-class-properties/test/fixtures
• update the readme if necessary

I'd love to take this issue if no one has grabbed it yet.
