Add ONAP core deployment type override

This patch makes heavy use of Orange accomplishments [1][2][3]. This
deployment override will probably succeed "minimal-onap.yaml" used in
e.g. "integration/bootstrap/vagrant-minimal-onap" setup.

Cassandra replicaCount is increased to 3 to allow reaching quorum.

+# This override file is used to deploy a core configuration. It is based on
+# minimal-onap.yaml and Orange accomplishments [1][2][3].
+# It includes the following components:
+# AAI, DMAAP, SDC, SDNC, SO (+ Cassandra)
+#
+# Minimal resources are also reviewed for the various containers
+# AAI: no override => to be fixed
+# DMAAP: no override
+# SO: no override
+# SDC: new values
+# SDNC: no override
+#
+# Replicas are set to:
+# AAI Cassandra: 1
+# Cassandra: 3 (to allow reaching quorum)
+#
+# In addition, some parameters are set to limit the memory footprint.
+#
+# It overrides the default ONAP parent chart behaviour to deploy
+# all of ONAP.
+#
+# helm deploy core local/onap --namespace onap -f core-onap.yaml
