Fixes #71 ### Motivation Pods are not restarting when config maps are changed after changing values.yaml file, so they need to be restarted manually in order to pick up new values from config map. ### Modifications As I mentioned `restartPodsOnConfigMapChange` flag for each component is added in values.yaml file whether to restart pods on configmap change or not, default is `false`. In statefulset templates for each component is added part which is adding annotation that contains hash of corresponding configmap if `restartPodsOnConfigMapChange` is `true`, which will cause pods to restart if corresponding configmap has been changed (https://helm.sh/docs/howto/charts_tips_and_tricks/#automatically-roll-deployments). ### Verifying this change - [ ] Make sure that the change passes the CI checks.
