Helm redis implementation
Added bitnami/redis into the redis folder from the helm chart repo https://charts.bitnami.com/bitnami
Updated Charts.yaml and values.yaml to include the new redis implementation. Included a .gitignore file to ignore .DS_Store files.
Tested the helm installation for redis locally in minikube.
helm install redis1 charts/redis -f charts/redis/values.yaml
used PING, set and get for testing from the redis-master via the redis-cli.
