Support "out_name" in input types

[Cito]

GraphQL-Core supports an out_name for input types which is used by Graphene for passing parameters with transformed names to Python (because Python likes snake_case instead of camelCase).

GraphQL-Core-Next should support a similar functionality that can be used by Graphene.

[Cito]

This is now fully supported and works the same as in GraphQL-core.

Is there a way to use this feature with an SDL-first approach?
I'm using build_schema to get my schema from the SDL, in addition with resolver methods on my root_value, and I would prefer my resolvers to get snake cased arguments instead of camel case.

You will need to patch the schema setting the out_names to the input fields. Something like this will probably do:

from graphql.pyutils import camel_to_snake

for field_name, field in schema.query_type.fields.items():
    for arg_name, arg in field.args.items():
        arg.out_name = camel_to_snake(arg_name)

Thanks for the tip, I'll try this ASAP!
