This implements the basics for the new app-password based authentication flow for our clients.
The current implementation tries to keep it as simple as possible and works the following way:
1. Unauthenticated client opens `/index.php/login/flow`
2. User will be asked whether they want to grant access to the client
3. If accepted the user has the chance to do so using existing App Token or automatically generate an app password.
If the user chooses to use an existing app token then that one will simply be redirected to the `nc://` protocol handler.
While we can improve on that in the future, I think keeping this smaller at the moment has its advantages. Also, in the
near future we have to think about an automatic migration endpoint so there's that anyways :-)
If the user chooses to use the regular login the following happens:
1. A session state token is written to the session
2. User is redirected to the login page
3. If successfully authenticated they will be redirected to a page redirecting to the POST controller
4. The POST controller will check if the CSRF token as well as the state token is correct, if yes the user will be redirected to the `nc://` protocol handler.
This approach is quite simple but also allows to be extended in the future. One could for example allow external websites to consume this authentication endpoint as well.

While the risk is actually quite low because one would already have the user session and could potentially do other havoc it makes sense to throttle here in case of invalid previous password attempts.

This makes the new `@BruteForceProtection` annotation more clever and moves the relevant code into it's own middleware.
Basically you can now set `@BruteForceProtection(action=$key)` as annotation and that will make the controller bruteforce protected. However, the difference to before is that you need to call `$responmse->throttle()` to increase the counter. Before the counter was increased every time which leads to all kind of unexpected problems.

* currently there are two ways to access default values:
OCP\Defaults or OC_Defaults (which is extended by
OCA\Theming\ThemingDefaults)
* our code used a mixture of both of them, which made
it hard to work on theme values
* this extended the public interface with the missing
methods and uses them everywhere to only rely on the
public interface

* try to reuse the old session token for remember me login
* decrypt/encrypt token password and set the session id accordingly
* create remember-me cookies only if checkbox is checked and 2fa solved
* adjust db token cleanup to store remembered tokens longer
* adjust unit tests
