CSV Annotations override pod annotations

Problem: If a pod template defined in a CSV's StrategyDetailsDeployment
includes an annotation defined for the CSV OLM will fail to install the
operator because the pod's annotations do not match those defined in
the CSV.

Solution: Pod template annotations defined in a StrategyDetailsDeployment are
overwritten by those defined in the CSV.
