The cluster CR doc is extremely long and in need of refactoring.
Now we have four new sub-topics for a host-based cluster,
PVC-based cluster, stretch cluster, and an external cluster.
Each of those topics has its own description and examples.
The main cluster CR topic still contains the details about
all the possible cluster CR settings.
