protondrive: add debug to help with #8860 FIXME DO NOT MERGE

This renames whitelabel authentication to traditional authentication and adds support for
the main Jottacloud service also here, as it can be used as an alternative to the
authentication based on personal login token for those who prefer it. Documentation
also adjusted correspondingly, and restructured the authentication section a bit more
since some of the sections that was under standard authentication in reality also
applies to the traditional authentication.

+# Rclone Code of Conduct
+
+Like the technical community as a whole, the Rclone team and community
+is made up of a mixture of professionals and volunteers from all over
+the world, working on every aspect of the mission - including
+mentorship, teaching, and connecting people.
+
+Diversity is one of our huge strengths, but it can also lead to
+communication issues and unhappiness. To that end, we have a few
+ground rules that we ask people to adhere to. This code applies
+equally to founders, mentors and those seeking help and guidance.
+
+This isn't an exhaustive list of things that you can't do. Rather,
+take it in the spirit in which it's intended - a guide to make it
+easier to enrich all of us and the technical communities in which we
+participate.
+
+This code of conduct applies to all spaces managed by the Rclone
+project or Rclone Services Ltd. This includes the issue tracker, the
+forum, the GitHub site, the wiki, any other online services or
+in-person events. In addition, violations of this code outside these
+spaces may affect a person's ability to participate within them.
+
+- **Be friendly and patient.**
+- **Be welcoming.** We strive to be a community that welcomes and
+  supports people of all backgrounds and identities. This includes,
+  but is not limited to members of any race, ethnicity, culture,
+  national origin, colour, immigration status, social and economic
+  class, educational level, sex, sexual orientation, gender identity
+  and expression, age, size, family status, political belief,
+  religion, and mental and physical ability.
+- **Be considerate.** Your work will be used by other people, and you
+  in turn will depend on the work of others. Any decision you take
+  will affect users and colleagues, and you should take those
+  consequences into account when making decisions. Remember that we're
+  a world-wide community, so you might not be communicating in someone
+  else's primary language.
+- **Be respectful.** Not all of us will agree all the time, but
+  disagreement is no excuse for poor behavior and poor manners. We
+  might all experience some frustration now and then, but we cannot
+  allow that frustration to turn into a personal attack. It's
+  important to remember that a community where people feel
+  uncomfortable or threatened is not a productive one. Members of the
+  Rclone community should be respectful when dealing with other
+  members as well as with people outside the Rclone community.
+- **Be careful in the words that you choose.** We are a community of
+  professionals, and we conduct ourselves professionally. Be kind to
+  others. Do not insult or put down other participants. Harassment and
+  other exclusionary behavior aren't acceptable. This includes, but is
+  not limited to:
+  - Violent threats or language directed against another person.
+  - Discriminatory jokes and language.
+  - Posting sexually explicit or violent material.
+  - Posting (or threatening to post) other people's personally
+    identifying information ("doxing").
+  - Personal insults, especially those using racist or sexist terms.
+  - Unwelcome sexual attention.
+  - Advocating for, or encouraging, any of the above behavior.
+  - Repeated harassment of others. In general, if someone asks you to
+    stop, then stop.
+- **When we disagree, try to understand why.** Disagreements, both
+  social and technical, happen all the time and Rclone is no
+  exception. It is important that we resolve disagreements and
+  differing views constructively. Remember that we're different. The
+  strength of Rclone comes from its varied community, people from a
+  wide range of backgrounds. Different people have different
+  perspectives on issues. Being unable to understand why someone holds
+  a viewpoint doesn't mean that they're wrong. Don't forget that it is
+  human to err and blaming each other doesn't get us anywhere.
+  Instead, focus on helping to resolve issues and learning from
+  mistakes.
+
+If you believe someone is violating the code of conduct, we ask that
+you report it by emailing [info@rclone.com](mailto:info@rclone.com).

 (Note that you can also replace `go build` with `make`, which will include a
 more accurate version number in the executable as well as enable you to specify
 more build options.) Finally make a branch to add your new feature

 If you are adding a new feature then please update the documentation.
 
+The documentation sources are generally in Markdown format, in conformance
+with the CommonMark specification and compatible with GitHub Flavored
+Markdown (GFM). The markdown format is checked as part of the lint operation
+that runs automatically on pull requests, to enforce standards and consistency.
+This is based on the [markdownlint](https://github.com/DavidAnson/markdownlint)
+tool, which can also be integrated into editors so you can perform the same
+checks while writing.
+
+HTML pages, served as website <rclone.org>, are generated from the Markdown,
+using [Hugo](https://gohugo.io). Note that when generating the HTML pages,
+there is currently used a different algorithm for generating header anchors
+than what GitHub uses for its Markdown rendering. For example, in the HTML docs
+generated by Hugo any leading `-` characters are ignored, which means when
+linking to a header with text `--config string` we therefore need to use the
+link `#config-string` in our Markdown source, which will not work in GitHub's
+preview where `#--config-string` would be the correct link.
+
+Most of the documentation are written directly in text files with extension
+`.md`, mainly within folder `docs/content`. Note that several of such files
+are autogenerated (e.g. the command documentation, and `docs/content/flags.md`),
+or contain autogenerated portions (e.g. the backend documentation under
+`docs/content/commands`). These are marked with an `autogenerated` comment.
+The sources of the autogenerated text are usually Markdown formatted text
+embedded as string values in the Go source code, so you need to locate these
+and edit the `.go` file instead. The `MANUAL.*`, `rclone.1` and other text
+files in the root of the repository are also autogenerated. The autogeneration
+of files, and the website, will be done during the release process. See the
+`make doc` and `make website` targets in the Makefile if you are interested in
+how. You don't need to run these when adding a feature.
