Middleware support

I just started looking into the new graphql version - first of all thanks for all the work, the Promise stuff is really going to make things simpler for us.

Before the update graphql supported multiple excutors/middlewares such as:

    import third_party.python.graphene as graphene
    from third_party.python.graphql.core.execution import Executor

    return graphene.Schema(
        query=Query,
        mutation=Mutation,
        name='Some Relay Schema',
        executor=Executor([ZipkinGraphqlMiddleware(), ThreadPoolExecutionMiddleware()]))

Now after looking into this, first of all the Executor is gone, but also from what I can see only one excutor/middleware is allowed per schema? Is that right, or am I just reading into the code wrong and I could just pass a list of middlewares?

As a side note: This is an extremely useful feature for us and do hope support is still here 😃

@syrusakbary Haven’t gotten around to it just yet. Been working on improving error-handling and Promise support first 😃 It is on my list for this week though, so will let you know once I got to it.
