Blindly removing openshift-operators-redhat during logging install

[dry923]

We are blinding removing the openshift-operators-redhat namespace during install/cleanup. This is bad practice as it may being used by other RH operators and could result in future problems. We should more selectively remove this namespace or even better, if we only remove what we need to add.
