Updated manifest for k8s persistent volume installation
When trying to follow the documentation for the manual installation of a Kubernetes cluster, I came across a small issue: When trying to apply the referred manifest for the persistent volume installation, I was given the error:
error: unable to read URL "https://openebs.github.io/charts/openebs-operator-1.6.0.yaml", server reported 404 Not Found, status code=404
In fact, when trying to access this URL in my browser, I encountered the same error (404, File not found).
Therefore, I decided to analyze the OpenEBS's GitHub, and there the developers advise to set up OpenEBS using Kubectl the following way:
$ kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml
In conclusion, this was the modification I have done in this pull request, as well as some modifications to the commands' outputs. To test if everything was running properly, I then added the newly created cluster to OSM (version 11.0.1), which gave no errors.
