[CONS-6524] Standardize OpenShift examples and clarify instructions for SCC/Log/APM

[JacksonDavenport]

What does this PR do?

Standardizing the OpenShift example configurations and instructions to a more consistent set up. This change simplifies the manual SCC instructions under the DaemonSet configuration, as with Helm/Operator this is entirely handled for you. Additionally clarifies some of the Logs/APM instructions, pointing towards the K8s>Distributions docs for more full configurations.
