* Replace `LoginRateLimiter.processLoginRequest` call by use of `RateLimiterMiddleware`
* Lowercase the email to avoid rate-limit bypass
* Remove unit test "when the users rate limit"
* Use `EmailHelper.parseEmail` to normalize email in `processLoginRequest`
This should address the `trim()` bypass
* Use `.trim().toLowerCase()` instead of `EmailHelper.parseEmail`
We can't use `EmailHelper.parseEmail`, else it breaks the test (and feature): "with username that does not look like an email"
* Add acceptance test for rate limit
* Add comment on rate limits
* Rename `rateLimiter` to `rateLimiterLoginEmail` for clarity
* Make the login rate limits configurable from the settings
