VOL-4904 - openonu python adapter

Makefile
--------
  o Added helper targets for running lint-helm and lint-chart locally.

README.md
---------
  o Replace legacy text for python openonu adapter with links to
    newer golang adapter

voltha-infra/Chart.yaml
-----------------------
  o Bump etcd and kafka chart versions to the latest available to fix a
    helm linting problem reported by jenkins.  Version edits were applied
    by an earlier job but not clear at the time if the correct vesrion(s)
    were applied.

misc/
=====
   o Update more copyright notices to 2023 forcing a jenkins job.

VERSION
=======
   o Revert VERSION file to 3.2.1, must have bumped it as part of splitting a pull request.

voltha-infra/Chart.yaml
-----------------------
   o Chart is dependent on votha/ so bump version string to try and correct jenkins job failure.
   o Update copyright notice.

Add a few more copyright changes to sanity check the build again.
