Local Helm chart for index_server

[chauvm]

Create a directory, e.g. deploy/charts/muopdb to store Helm chart definition. We will publish the chart to a public registry in another task. The acceptance criteria of this task is to have one pod of the index server up and running in a local Kubernetes cluster with a single command helm install muopdb deploy/charts/muopdb.

Suggested steps:

• initialize a Helm chart
• create a StatefulSet for Index Server.This docker-compose file should give some ideas how their commands should look like.
• values.yaml: think of appropriate default values for important parameters, e.g. resources limits and requests to run MuopDB
