Description

This PR

• fixes the linking problem between SubGraph and ApiDefinition CRs. Previously, we were not updating SubGraph CR after breaking its relationship with a particular ApiDefitinition.
• adds a new way to use Reconciler in integration tests. So, I wrapped e2e-framework's client with controller-runtime's client and used the controller-runtime client as the real one. With this approach, you will be able to run directly Reconcile function of a specific controller from now on.
• adds some unit tests for processSubGraphExec method in the ApiDefinition controller.
• adds e2e tests for ApiDefinition with subgraph graphql configuration.
• adds a new field called TYK_VERSION to tyk-operator-conf in bootstrapping. e2e tests of GraphQL federation were failing on Tyk v3.2 because gql federation is not supported on Tyk v3.2. With this new secret field, we are able to identify running Tyk version on e2e tests and to skip particular test suites, like graphql federation, on certain Tyk versions.
