ci: create ceph-csi-config ConfigMap for external storage tests

Browse Source 
The StorageClasses that get deployed for the Kubernetes e2e external
storage tests reference a ConfigMap that contains the connection details
for the Ceph cluster. Without this ConfigMap, Ceph-CSI will not function
correctly.

The files in this directory are used by the k8s-e2e-external-storage CI job.
This job runs the [Kubernetes end-to-end external storage tests][1] with
different driver configurations/manifests (in the `driver-*.yaml` files). Each
driver configuration refers to a StorageClass that is used while testing. The
StorageClasses are created with the `create-storageclass.sh` script and the
driver configuration refers to a StorageClass that is used while testing.
The StorageClasses are created with the `create-storageclass.sh` script and the
`sc-*.yaml.in` templates.
The Ceph-CSI Configuration from the `ceph-csiconfig` ConfigMap is created with
`create-configmap.sh` after the deployment is finished. The ConfigMap is
referenced in the StorageClasses and contains the connection details for the
Ceph cluster.
