Consume Topology CR by reference

This patch provides more granular control over Pod placement and
scheduling through the Topology CR integration introduced in [1].
In particular it provides:

- a new API parameter (TopologyRef) defined for each Component that
  allows to reference an existing Topology CRs in the same namespace

- the operator logic that retrieves and processes the referenced
  Topology CR through the functions provided by lib-common [2]

- enhanced StatefulSet and Deployment configuration that incorporates
  the processed Topology

- kuttl test to verify a referenced topology has been applied to the
  StatefulSet and the resulting Pods

Note that webhooks are in place to prevent referencing a Topology from a
different namespace (which is not a supported scenario).
