* Cleaning up the documentation folder
This change cleans up the documentation folder in the CLI repo. The
changes are the following:
* Delete old content that is invalid moving forward.
* Move cli-installation-scenarios to the `specs` sub-folder.
* Add a sub-folder for documentation that deals with working with the repo
* Add a general sub-folder
* Finally, change the README.md to reflect this.
Also, this change adds a document that covers CLI UX guidelines for
authors of new commands.
* Firt round of PR feedback changes
The README.md contained some errors, corrected those. Removed the
native compilation bits for now.
Added an issue filing guide to make the issue process slightly better so we can
triage better.
