PR for #9

[leochr]

@arturdzm Thanks for the PR. Looks good. Some updates needed. If possible, please submit suggested changes via a separate commit, so it'll be easy to review just that. Thanks.

• There are few references to olo- in e2e.sh and e2e-minikube.sh

• config/manifests/kustomization.yaml: Websphere-liberty.v0.0.0 should be websphere-liberty.v0.0.0 (x-descriptor for service binding secret is missing from bundle's CSV due to this)

• registry.connect.redhat.com/ibm/websphere-liberty-samples:springPetClinic should be registry.connect.redhat.com/ibm/open-liberty-samples:springPetClinic

• description section in bundle's CSV is specified twice. The content is added from an *.md file now (Jason added some changes). Deleting the description section from config/manifests/bases/websphere-liberty.clusterserviceversion.yaml and generating bundle should resolve it.

• controllers/webspherelibertyapplication_controller.go - following value should be finalizer.webspherelibertyapplications.liberty.websphere.ibm.com

const applicationFinalizer = "finalizer.liberty.websphere.ibm.com"

• main.go: it should include liberty I believe Below value is fine (Leo)
  LeaderElectionID: “7111f50b.websphere.ibm.com”,
• please change image references cp.stg.icr.io/websphere-liberty-operator to icr.io/cpopen/websphere-liberty-operator
