Typings are messed up

When importing version 2.0.3, TypeScript types are completely messed up:

1. It’s impossible to use Promises as returned methods. Taking one method as example: exists(options: any, callback?: any): void;. The documentation says that it can be used with Promises too (and it works), but the type definition shows return type as void.
2. Types are just wrong. In the same method, the JSDoc definition says that the first argument (options) is optional, but the method signature marks it mandatory.
3. The library uses any as type anywhere. Options dictionaries, callbacks, etc: these are things that should be explicitly typed.
4. The library still uses JSDoc types everywhere, which should be migrated to TypeScript definitions.

Almost all methods have wrong typings. I showed one just as example.

We haven’t moved to 2.x yet. But I see in the team’s 2.1.0 release (https://github.com/googleapis/nodejs-storage/releases/tag/v2.1.0) that they “disable TypeScript as we continue to annotate the project with types”. So it sounds like they’re completely turning off the d.ts file generation for now. I tried updating my example project to 2.1.0 to test this, but they haven’t published 2.1.0 to NPM yet. I’m hoping when they publish it, we can go back to using latest version without TypeScript issues.
