[VOL-5020] Update helm charts for repo:voltha-tracing

bbsim-sadis-server/Chart.yaml
voltha-infra/Chart.yaml
voltha-stack/Chart.yaml
voltha-tracing/Chart.yaml
voltha/Chart.yaml
-----------------------------
  o Update bbsim chart version to v0.3.6
  o Re-edit a few chart versions, voltha-tracing reported as a duplicate.
  o Just updated a little while ago, wondering if we have a timing issue with
    an asynchronous jenkins updating repo:cord-helm-charts + rebuild index.
