Add ObservedGeneration to the sub Resources

[fmount]

This patch does a few things:

1. it adds observedGeneration to the sub custom resources
2. it proposes to bump the observedGeneration at the beginning of the reconciliation loop (metadata.observedGeneration behaves differently across CRDs knative/serving#4937)
3. it checks, at the top level, if the observedGeneration matches with the metadata.generation assigned to the subCR(s); if it's the latest version, the condition is mirrored
4. before marking DeploymentReadyCondition as True in the subCRs, observedGeneration is compared with the generation of the Deployment/Statefulset
5. it updates the functional tests and bumps both lib-common/modules/test and lib-common/modules/common
