Monitor GraphQL with Opentracing (Jaeger)

Closes #48726

See merge request gitlab-org/gitlab-ce!26981

Extends existing graphql's tracer with opentracing measurements. Because
it also adds Tracing::Graphql class (for opentracing), it also renames
Graphql::Tracing class to Graphql::GenericTracing to minimize confusion
with similar class names.
