Allow user to hook into Breadcrumb in SentryInstrumentation

[ooraini]

Problem Statement

I want to add more data into the breadcrumbs generated by SentryInstrumentation,. As a use case, I want to add any parameter named id when resolving any field: user(id: "..."). I could use context data, but with nesting it will not work. Example breadcrumb from sentry.io:

{
field: createXyz,
object_type: Mutation,
path: /createXyz,
type: createXyzPayload

...hook for more data

}

There are two places where breadcrumbs are used in SentryInstrumentation: beginExecuteOperation and instrumentDataFetcher. I'm not sure about beginExecuteOperation, but instrumentDataFetcher is mostly where I want to enrich the breadcrumb.

Solution Brainstorm

Nested class in SentryInstrumentation

interface DataFetcherBreadcrumbEnricher {
        void enrich(DataFetchingEnvironment environment, Breadcrumb breadcrumb);
}
