* Consolidate YAML files [part-5]
This PR relocates the yaml files used in stateless application
guestbook. This PR also fixes the list numbering and code block
problems in the page.
Note that neither code blocks nor note callouts live happily inside a
numbered list, so this PR moves them out of such lists.
* Update examples_test.go
Changes that will help upcoming consolidation work:
- Add variable `githubWebsiteRaw` to config.toml to facilitate building
links to raw YAML files
- Revise `codenew` shortcode to generate links to raw YAML files instead
of github.com file view;
- Rename `artifacts` directory to `examples` to better reflect its usage;
Accompanied changes as show cases:
- Moved `deployment.yaml`, `deployment-update.yaml` and
`deployment-scale.yaml` to the new `examples/application` subdirectory;
- Removed duplicate instances of the above YAML files in other
directories;
- Update example_test.go to test the relocated YAML files and removed
testing for files that no longer needed.
