✨ prototyping dynamic graphql handler for catalogd

[joelanford]

Veeeeeerrrrrrrrrry rough around the edges PR that gets a graphql handler added to the catalogd server (behind a feature gate). Not really happy at all yet with the library refactoring that adds the Indexer and Index types. But for now it at least gets the job done for this prototype.

The idea here is that when we store an FBC, we build up a graphql schema dynamically based on the content of the FBC. The result being that catalogd is still a "dumb pipe" for FBC data. The GraphQL API is directly derived from the FBC API (or at least the parts of the FBC API that are in use somewhere in the served FBC).

To play with it, I've enabled the GraphQL explorer handler, so you can:

make run-experimental
kubectl port-forward -n olmv1-system service/catalogd-service 8443:443

And then open https://localhost:8443/catalogs/operatorhubio/api/v1/graphql

And here's are some interesting queries to run:

Bundle search metadata

{
  olmBundle {
    package
    name
    properties(type: "olm.csv.metadata") {
      value(jq:".annotations | [to_entries[] | select(.key | test(\"features|valid-subscription|description|capabilities|categories\"))] | from_entries")
    }
  }
}

What OLMv1 operator-controller actually needs for resolution:

{
  olmChannel {
    package
    name
    entries {
      name
      replaces
      skips
      skipRange
    }
  }
  olmBundle {
    package
    name
    image
  }
}
