Create an individual namespace for user to operate

[jianh619]

What steps did you take and what happened:

User need provide config such as kubeconfig/pullsecret/product settings etc , and store it by either secret or configmap in a namespace . It's not suitable to just use crossplane install namespace crossplane-system for following reasons:

• The crossplane installed namespace is different from OCP and k8s , gitops experience is un-consistent
• All these config are user data , it should be protected by user themselves( it may be deleted when uninstalling gitops tools)

What did you expect to happen:

Create an individual namespace to user to operate , it may not have to customize by user itself .

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

Environment:

• Minikube/KIND version:
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):
• Instana version:
• Crossplane version:
