Feature request: Enable middleware functionality for AppSyncResolver

[TonySherman]

Use case

The middleware functionality for the event handler REST APIs provides a really nice way to work with requests but the AppSyncResolver does not have the same API available to it.

Solution/User Experience

Ideally, the AppSyncResolver would have the same dev experience as the REST API middlewares:

app = AppSyncResolver(middlewares=[my_global_middleware])

@app.resolver(type_name="Query", field_name="getTodo", middlewares=[another_middleware])
