Rust test cases for /v1/graphql requests

[jmbrunskill]

Expected Behaviour

Currently our /v1/graphql integration test are in typescript and part of the dataservice
We want something to test with our side of this ecosystem

Possible Solution

• Service tests, similar to other test cases relying on a subset of universal codes data
• Perhaps translate the jest tests into k6 tests?

The CI build is also now failing because of that weird cross-fetch can't be defined twice error... so will be extra nice when these test are reimplemented and that non-compiling code can be put to rest 😌
