For manual deploying DL feeder to k8s cluster

Update db script to connect to Kafka using encrypted connection.
If your testing Kafka is not encrypted, change 'secure' in table 'kafka'
to 0.

Steps to manually deploy feeder to ONAP k8s cluster:
Change IPs with your env setup in feeder-deployment.yaml.

kubectl create -f feeder-deployment.yaml
kubectl create -f feeder-service.yaml

Find DL port at nodes:
kubectl get svc --output=wide -n onap |grep datalake

Testing:
curl http://r-node-1:31157/datalake/v1/feeder/status
