add operatorhub bundle files

[pb82]

Add operatorhub bundle files for the 1.3.0 release

Verification steps:

1. An OpenShift 4 cluster is needed
2. Login to your OpenShift 4 cluster with oc and create the following OperatorSource:

apiVersion: operators.coreos.com/v1
kind: OperatorSource
metadata:
  name: pb82-operators
  namespace: openshift-marketplace
spec:
  type: appregistry
  endpoint: https://quay.io/cnr
  registryNamespace: pb82
  displayName: "Integreatly Operators"
  publisher: "Integreatly"

oc create -f ./operator-source.yaml

3. Make sure the operator source is valid:

oc get operatorsource -n openshift-marketplace

There should be a value like this:

pb82-operators        appregistry   https://quay.io/cnr   pb82                  Integreatly Operators   Integreatly   Succeeded   The object has been successfully reconciled   22m

4. In the OpenShift console, create a new project named grafana
5. In the OpenShift console, navigate to Catalog -> OperatorHub
6. In the left panel under Provider Type there should be a category Custom
7. It might take a minute for OpenShift to recognize the new OperatorSource, refresh the page if it's not yet visible.
8. Under the Custom category, you should find the Grafana Operator.
9. Click on it, then select Install (make sure that the Grafana project is selected)
10. Click on the Suscribe button and wait for the installation to finish.
11. Make sure the operator is running in the grafana namespace and does not have any errors in the log.
12. Create a Grafana Instance: Grafana.yaml and GrafanaWithRoute.yaml from the examples directory will both work, GrafanaWithIngressHost.yaml will only work on Kubernetes.
13. Create dashboards and a data source and make sure everything works as expected.
14. Log into the Grafana instance (credentials can be found in the CR) and make sure that the dashboards and data source have been created.

@pb82 Looks really good, great work. I have verified it using the steps provided. I have a few questions

1. Who should the publisher be, Integreatly or Red Hat?
2. Should you be allowed to create multiple grafana CRs in the same namespace? (Currently this is not the case). I can't imagine this would be allowed but wanted to check.
3. If a GrafanaDashboard CR is updated with new json, should this be reflected in Grafana. This doesn't seem to be the case right now.
