- Adds a new "infrastructure" section to the docs, which describes
architecture, administration and troubleshooting (fixes bug 1165259).
- Adds code comments to any deployment-related files in the repository.
- Adds documentation for the various ways in which users can access
Treeherder data (fixes bug 1335172).
- Reorganises the structure of some of the existing non-infrastructure
docs, to make the documentation easier to navigate.
Since they are out of sync with `Procfile` and long term are best replaced
with one of the solutions in bug 1318020.
The development setup instructions have been updated to stop recommending
gunicorn, since Django's runserver is more appropriate for beginners
(and I'm pretty sure the memory leaks seen previously no longer occur).
The latest policy used in the report-only header has been working well
on production (the violation reports logged to New Relic are only from
scripts injected by browser addons), so we're ready to start enforcing
the policy by using the real `Content-Security-Policy` header name.
NB: When features are added in the future, PR authors and reviewers will
need to remember to update the policy if needed (for example to add domains
to the `connect-src` directive). The CSP header is not enabled when using
`webpack-dev-server` (it would break dev source maps and react-hot-loader)
so if in doubt test locally (using `yarn build` and serving via Django
runserver) or on prototype first.
See:

Also remove all Karma support and update the docs to only mention ``Jest``.
One of the test files was testing some AngularJS filters. I converted these
tests to test the equivalent helper functions.
Switches from Sphinx to MkDocs, since it:
* supports Markdown natively without requiring hacks like `eval_rst`
* validates inline links, ensuring that they are not broken
* has a more pleasant live-reloading dev-server
* supports the nicer looking mkdocs-material theme
* is a third of the size of Sphinx (including deps)
The theme change is now possible since Read the Docs have just started
supporting use of custom themes (previously they would override the theme
and use `readthedocs` theme regardless).
Since it's more reliable (and strict) at code formatting than ESLint.
We use it via an ESLint plugin, and so disable the style-related AirBnB
preset rules, leaving the AirBnB guide to handle only correctness and
best practices rules.
It's highly encouraged to use an IDE integration or Git commit hook
to run Prettier (or `yarn lint --fix`) automatically. See:
* https://prettier.io/docs/en/editors.html
* https://prettier.io/docs/en/precommit.html
We may consider enabling a git commit hook out of the box (using eg
Husky) in the future, however they have previously been known to
interfere with partial-staging workflows, so would need to test the
fixes they have made for them thoroughly first.
In future PRs we may also want to start formatting JSON/CSS/Markdown
using Prettier too.
Neutrino controls our frontend linting, transpilation, source-maps,
testing, dev-server and optimisation of production builds.
Highlights of the upgrade are:
* Major version updates to the individual tools within (such as webpack,
Babel and ESLint), significantly improving performance, fixing
transpilation/minification correctness bugs, adding support for newer
ECMAScript features, and increasing linter coverage.
* Hot reloading in the dev server now works for all entry-points and not
just the jobs view, shortening the feedback cycle.
* Reduced bundle size due to webpack 4's tree shaking, scope hoisting,
automatic shared/vendor code chunk splitting (no need for the manually
maintained 'vendor' list).
* CSS is now extracted out of JS, which improves performance, reduces
bundle size and prevents the initial white flash of un-styled content.
* Support for dynamic imports/code splitting (needed for bug 1502192).
* Support for Jest via a new Jest preset (unblocks bug 1364045).
* Support for public class field declarations (unblocks bug 1480166).
* Improved source-maps (increases the quality of production exception
trace-backs and fixes several debugger breakpoint bugs).
* Reduced amount of custom configuration required for our fairly complex
frontend needs, reducing maintenance burden and allowing for easier
future Neutrino upgrades.
In addition this PR:
* Fixes the WhiteNoise `immutable_file_test()` regex, so that it now
correctly enables browser caching of images, fonts and source maps.
* Enables webpack-dev-server's overlay feature, which displays any
compilation errors in the browser, saving having to switch back
to the console (this can be enabled for warnings too if desired).
* Enables webpack-dev-server's automatic browser-opening feature,
which saves having to manually navigate to `localhost:5000` after
running `yarn start`.
* Switches Karma tests to run Firefox in headless mode, reducing the
workflow disruption when running `yarn test`.
* Uses the new webpack `performance` option to enable maximum asset
file size thresholds, to help prevent bundle-size regressions.
* Rewrites the `package.json` script commands so that they now work
correctly on Windows, even when setting environment variables.

Renaming as a separate commit since otherwise Git was struggling to
identify the renames, making the diff harder to review.
`index.rst` has been left unchanged, since we still want to use the
`toctree` directive for now.
