Add option for simpler GraphQL resource names

[goodspark]

The current ddtrace GraphQL integration sets the full query as the resource name. This is fragile for monitoring and metrics purposes because a simple field change will result in a completely new name. In addition, it's kind of unsightly to see a resource name that's so long.

As an example, take a look at ddtrace-graphql. Normally, I'd just use that, but it's out of date and incompatible with the latest versions of ddtrace as well as graphql.
