Document Installation Process Without Operator Lifecycle Manager

[hi-artem]

Documentation link

https://github.com/PaloAltoNetworks/prisma-cloud-compute-operator/blob/main/docs/Kubernetes/kubernetes.md

Describe the problem

Step 3 suggests to install Operator Lifecycle Manager, however it brings up some more resources in the cluster which Kubernetes administrators wouldn't necessary want to manage.

Suggested fix

Add another option in step 3, showing installation from source. For example:

Clone repo and apply yaml definitions to your cluster using kubectl:

git clone https://github.com/PaloAltoNetworks/prisma-cloud-compute-operator.git && \
  kubectl apply -k prisma-cloud-compute-operator/config/deploy
