Error in first Voltha deployment first time it is installed

The first time Voltha is deployed, we see an error in the installation of the etcd dependency:

*******************

helm install -n voltha voltha

2018/04/26 09:34:46 warning: skipped value for replicas: Not a table.

Error: apiVersion "etcd.database.coreos.com/v1beta2" in voltha/charts/etcd-operator/templates/etcd-cluster-crd.yaml is not available 

********************

The woraround for now to install voltha without etcd enabled, delete it and the install voltha with etcd enabled:

*********************

helm install -n voltha --set etcd-operator.customResources.createEtcdClusterCRD=false voltha 

helm delete --purge voltha

helm install -n voltha voltha

*********************

But we need a better fix for this issue and this bug is to track it.
