RFC: Add a new decorator to classify bindable classes/providers

[raymondfeng]

To allow boot to discover and bind certain artifacts such as providers, controllers, repositories, or other classes, a decorator is desirable to add metadata to the class. For example:

@bindable({type: 'controller', name: 'my-controller', tags: [], scope: BindingScope.SINGLETON})
class MyController {
}

@bindable({type: 'booter', name: 'swagger-booter', tags: [], scope: BindingScope.SINGLETON})
class SwaggerBooter {
}

@bindable({type: 'provider', name: 'swagger-booter'})
class LogLevelProvider {
}

Can you update the issue description with what the full metadata should look like?
