Typescript-node - Should use the `async` keyword on methods returning a promise

I installed swagger-codegen@2 on a mac to make sure that typescript-node was included as a language. When generating a Typescript-node API there is no need to include bluebird as a dependency. Also the async methods that return a promise should be defined with the async keyword. For example:

public methodName(): Promise<type>
should be
public async methodName(): Promise<type>

Description

Swagger-codegen version

V2.4.1

Command line used for generation

swagger-codegen generate -i swagger.json -l typescript-node

Steps to reproduce

Any typescript-node generation

Start from the typescript-node generation entry point used by swagger-codegen generate -i swagger.json -l typescript-node, then inspect the templates and dependency declarations that produce the generated API. Generate a sample API to verify that bluebird is no longer required and that promise-returning methods use async.
