Add some code to generate a basic markdown file documenting a generated
API. Generate this document for the API in
satellite/console/consoleweb/consoleapi/gen.
The documentation is not completely correct, as it may include some
values in the request body that are not actually usable by the
requester. This can be fixed by making sure all types used within the
generated API are properly annotated with `json` tags.
