Adding cassandra service with a separate yaml file.

- Left the file samples/scenarios/service_delivery_controller_opnfv.yaml unchanged.
- Added a yaml definition of Cassandra StatefulSet and its service into a separate file under tools directory
- Cassandra Service run with 1 replica
- Deleted 'data-plane-ns' and use 'default' instead for cassandra containers.
- Revoked changes for samples/scenarios/service_delivery_controller_opnfv.yaml.
- Added new line (Wutien suggested it)

+# The addition below can be executed after the invocation of
+# the original service_delivery_controller_opnfv.yaml
+# by invoking:
+#  % kubectl create -f <(istioctl kube-inject --debug -f cassandra.yaml)
+#
+#
+#
+# Cassandra Statefulset
+#
+# Assumption:
+#    - The Cassandra Statefulset right now assumes that
+#    the service is deployed in the 'default' namespace
+#    therefore the environment variable CASSANDRA_SEEDS is set to
+#    "cassandra-0.cassandra.default.svc.cluster.local" below.
+#    if you want to use your own name space other than 'default'
+#    the value becomes:
+#    "cassandra-0.cassandra.<NAMESPACE_NAME>.svc.cluster.local"
+#    note that this value rely on a functioning DNS on kubernetes to resolve the IP
+#
+#    This static method can be made dynamic by using Helm
+#    or bash script to replace the namespace on the fly. 
+#
+#   - Cassandra launch only 1 replica in the cluster
+#     to dynamically scale up or down, you can use:
+#     kubectl edit statefulset cassandra
+#     and edit the value of the replica key
+#
