Discussion: getAutocompleteSuggestions

Hi all,

I was thinking to add a new property `graphQLType` into items of returned array from [getAutocompleteSuggestions](https://github.com/graphql/graphiql/blob/v2.0.1/packages/interface/src/getAutocompleteSuggestions.js#L53), which is a type of [GraphQLType](https://github.com/graphql/graphql-js/blob/v14.4.2/src/type/definition.js#L46) and a type object related to the returned label. The reason I was thinking to do it is [here](https://github.com/graphql/graphiql/pull/902#pullrequestreview-267521414).

However, I noticed that this change would affect applications and libraries using `getAutocompleteSuggestions`. One of these is [graphql-language-service-server](https://github.com/graphql/graphiql/tree/v2.0.1/packages/server). I think this library doesn't like this change because it's not only necessary at all but also increases the amount of transferred data.

So I'm now thinking I'll create a new function instead in [codemirror-grpahql](https://github.com/graphql/codemirror-graphql/tree/v0.8.3) that returns `graphQLType` property instead of `detail` property. Also, some functions used in `getAutocompleteSuggestions` can be also used in this new function so I want to export those functions from `getAutocompleteSuggestions` and [graphql-language-service-interface](https://github.com/graphql/graphiql/tree/v2.0.1/packages/interface) and use them in the new function.

What do you think of this idea? Thanks for your opinion in advance.
