### Pull Request Checklist
This PR add support for hcaptcha.com as an alternative to Google
ReCaptcha. It also makes possible for user to customize ReCaptcha URL
when needed. (Such as use recaptcha.net instead of www.google.com)
This feature needs manual test cuz it involves 3rd party _captcha_.

This makes the following changes:
* The various `Defaults` functions are now responsible for setting sane defaults if `generate` is specified, rather than hiding them in `generate-config`
* Some configuration options have been marked as `omitempty` so that they don't appear in generated configs unnecessarily (monolith-specific vs. polylith-specific options)
* A new option `-polylith` has been added to `generate-config` to create a config that makes sense for polylith deployments (i.e. including the internal/external API listeners and per-component database sections)
* A new option `-normalise` has been added to `generate-config` to take an existing file and add any missing options and/or defaults
* Rate limiting changes
This makes the following changes:
* For logged in users, the rate limiting now applies to the device session rather than the remote IP address;
* For non-logged in users, the rate limiting continues to apply to remote address as it does today;
* It is now possible to add user IDs to the `exempt_user_ids` option under `rate_limiting` to exclude bots from rate limiting;
* Admin and appservice users are now exempt from rate limiting by default.
* Fix build with media API
* Add restrications for open registration
* Make enable open registration a parameter
* Enable registration for CI
* Update error message
* Shuffle things around a bit
* Add a warning at every startup just to be extra annoying
* Ignore shared secret when warning about open registration, since it's not strictly required when it is set if registration is otherwise enabled
* Make CI happy?
* Add missing parameter; try new parameter in upgrade-test
