Env-based SAML uses the "Apache auth" mechanism to log users in. In this
code path, we first delete all existin auth tokens from the database,
before a new one is inserted. This is problematic for concurrent
requests as they might reach the same code at the same time, hence both
trying to insert a new row wit the same token (the session ID). This
also bubbles up and disables user_saml.
As the token might still be OK (both request will insert the same data),
we can actually just check if the UIDs of the conflict row is the same
as the one we want to insert right now. In that case let's just use the
existing entry and carry on.

Once 2FA is enforced for a user and they have no 2FA setup yet this will
now prompt them with a setup screen. Given that providers are enabled
that allow setup then.

Generate a notification to generate backup codes if you enable an other
2FA provider but backup codes are not yet generated.
* Add event listner
* Insert background job
* Background job tests and emits notification every 2 weeks
* If the backup codes are generated the next run will remove the job

If the 2FA provider registry has not been populated yet, we have to make
sure all available providers are loaded and queried on login. Otherwise
previously active 2FA providers aren't detected as enabled.

This adds persistence to the Nextcloud server 2FA logic so that the server
knows which 2FA providers are enabled for a specific user at any time, even
when the provider is not available.
The `IStatefulProvider` interface was added as tagging interface for providers
that are compatible with this new API.

However due to the nature of what we store in the token (encrypted
passwords etc). We can't just delete the tokens because that would make
the oauth refresh useless.

On a remembered login session, we create a new session token
in the database with the values of the old one. As we actually
don't need the old session token anymore, we can delete it right
away.

* Store the auth state in the session so we don't have to query it every
time.
* Added some tests
