Apollo GraphQL Federation support

[tzejohn]

Feature description

Not sure if this is something that is already supported yet or not, but the Micronaut framework is not listed on the Apollo Federation supported subgraph library page (https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs/). Is this something that someone is already working on?

@jeremyg484 any update on this?

[jeremyg484]

@sdelamo I've investigated it, and I don't immediately see any reason why we shouldn't be compatible. It mainly requires the user to manually include the added support from the federation-graphql-java-support when building the GraphQL object in a @Factory bean.

To be included in the list of "supported libraries", we will need to implement their compatibility tests and submit a PR here: https://github.com/apollographql/apollo-federation-subgraph-compatibility

The instructions for implementing the tests are here: https://github.com/apollographql/apollo-federation-subgraph-compatibility/blob/main/SUBGRAPH_GUIDE.md

I have moved this to under consideration
