[OIDC] ​Disable other login methods

[madduck]

Description

When OIDC is configured and works, it would be good to completely hide all other login options (username & password), maybe even automatically redirect to SSO instead of even requiring the user to click "Continue with OIDC".

For when OIDC doesn't work and the admin needs to log in, a query string like ?allauth=1 could be parsed.

Use case

In the corporate setting with SSO, users should never be tempted to do anything other than SSO, and it's also a source of potential confusion when the software suggests to login with an email address.

Anything else?
