Create process for adding additional commands to the bbctl bbUpdater helm chart

Currently the bbctl helm chart is configured to run bbctl version -U -A internally. This is defined here. Determine a process that can be employed to add additional commands to the bbctl helm chart that can optionally be enabled by end-users using the chart.

Each subsequent issue in this epic has two components:

• Create a helm chart configuration
• Create the dashboard for the specific feature

This issue defines the process used to complete those first tasks.

Acceptance Criteria

• Process should be documented in the docs/ folder of this repo
• The process should limit the amount of duplication of helm templates where able, leaning more on variables and define clauses.
• The resulting commands should be able to be toggled by setting a simple value in the values.yaml file
• Each command should be run in its own CronJob resource
• All created cronjobs should be tagged or labeled in such a way that we can create a dashboard later to see the output of ALL running bbctl jobs in-cluster on a dashboard to be implemented in #201 (closed)
