PROBLEM:
The "Hello Holos" tutorial has hardcoded code blocks and hasn't been
updated to use the automated testscript workflow.
SOLUTION:
* Create a test for the Hello Holos tutorial.
* Create a testscript for the Hello Holos test.
* Update the Hello Holos MDX file to load in data from the testscript directory.
OUTCOME:
The code content in the Hello Holos tutorial now comes directly from the
testscript workflow.
Similar to the Clusters topic, add a topic about configuring multiple
environments. This likely needs some work, the example is a bit
contrivied but at least shows how we can look up attributes, then use
those attributes to look up additional configuration from platform-wide
configuration data.
This commit removes the extra `./platform` argument from any of the
current tutorial/topic docs to reflect the change that was made to
`holos render platform` in version `0.100.0`.
Version doesn't make as much sense since we're doing a hello world
tutorial.
Also consolidate the values information into one step, and consolidate
the breaking it down section to make it shorter and clearer.
A tree view of the `holos-tutorial/` directory should give readers a
quick, high-level understanding of the folder structure of a typical
Holos platform project.
Add a helm values tutorial which is a cut down version of the v1alpha4
helm guide. The httpbin kustomize will immediately follow building on
the prometheus and blackbox charts.
