Subject: [PATCH] Add ability to pass `execution_context_class` to
 `GraphQLView.as_view()` (#1109)

* Add ability to pass `execution_context_class` to `GraphQLView.as_view()`

Currently when passing `execution_context_class` like this:

```
GraphQLView.as_view(execution_context_class=CustomContext)
```

you get the following error from `View.as_view()`
```
TypeError: GraphQLView() received an invalid keyword 'execution_context_class'. as_view only accepts arguments that are already attributes of the class.
```

this PR fixes the `hasattr` check in `.as_view`.

Fixes: #1072

* make black happy

removed whitespace
