Document task-runner chart values & usage
We currently have limited documentation for the possible values and configurations of the task-runner.
- We do have most of the viable options populated within "the grand list" at
doc/installation/command-line-options.md
(I dislike this list!). - We do not have a documentation page explicitly for this chart. We absolutely should, considering how critical and useful it is to the operation & maintenance of this chart.
- Said document should be linked from the list of sub-charts, troubleshooting, and development pages.
