The initializers including this were doing so at the top level, so every object
loaded after them had a `current_application_settings` method. However, if
someone had rack-attack enabled (which was loaded before these initializers), it
would try to load the API, and fail, because `Gitlab::CurrentSettings` didn't
have that method.

To fix this:

1. Don't include `Gitlab::CurrentSettings` at the top level. We do not need
   `Object.new.current_application_settings` to work.
2. Make `Gitlab::CurrentSettings` explicitly `extend self`, as we already use it
   like that in several places.
3. Change the initializers to use that new form.

Upon inspection of logs, there were a number of fields not filtered. For example:

* authenticity_token: CSRF token
* rss_token: Used for RSS feeds
* secret: Used with Projects::UploadController

Rails provides a way to match regexps, so we now filter:

* Any parameter ending with `_token`
* Any parameter containing `password`
* Any parameter containing `secret`
