Investigate automated generation of beta-site content related to CLI commands

[jessicaschilling]

In the legacy docs site, CLI command reference pages are auto-generated from their respective repos. Investigate best way to do this in VuePress, keeping in mind concerns raised by @Stebalien in #227 and overall UX of the content that is generated.

Implementation of this effort lives in issue #227.

Closing, since this issue has been consolidated into the overall effort for improving/automating API/CLI documentation in #393.
