bashbot-v2.0.0

Release v2

This major version bump batches a few breaking changes in one release.
- First, we migrated to the latest slack go api to leverage the new socket mode. This will require existing bashbot instances to get a new slack token that uses the proper scopes/permissions, and not the classic app that v1 used.
- Next we migrated to the golang lib cobra, and the command line arguments/parameters have changed.
- We also added a helm chart and automated KinD tests to run on every PR
- Finally, we have migrated the configuration format from json to yaml
