authentik: Release 2021.4.4

## Headline Changes - Configurable Policy engine mode In the past, all objects, which could have policies attached to them, required *all* policies to pass to consider an action successful. You can now configure if *all* policies need to pass, or if *any* policy needs to pass. This can now be configured for the following objects: - Applications (access restrictions) - Sources - Flows - Flow-stage bindings For backwards compatibility, this is set to *all*, but new objects will default to *any*. - Expiring Events Previously, events would stay in the database forever, and had to eventually be cleaned up manually. This version add expiry to events with a default timeout of 1 Year. This also applies to existing events, and their expiry will be set during the migration. - New UI While the UI mostly looks the same, under the hood a lot has changed. The Web UI is now a Single-page application based on rollup and lit-html. This has several consequences and new features, for example: - You can now see a user's OAuth Access/Refresh tokens and the consents they've given - You can now see a per-object changelog based on the model_create/update/delete events being created. - A new API Browser is available under `https://authentink.company/api/v2beta/` - Several new charts, new pages and quality-of-life improvements - Credentials of objects are no longer shown while editing them - Deprecated Group membership has been removed. ## Minor changes - You can now specify the amount of processes started in docker-compose using the `WORKERS` environment variable. ## Fixed in 2021.4.4 - *: make tasks run every 60 minutes not :00 every hour - outposts: check for X-Forwarded-Host to switch context - outposts: improve update performance - outposts: move local connection check to task, run every 60 minutes - providers/oauth2: add proper support for non-http schemes as redirect URIs - providers/oauth2: fix TokenView not having CORS headers set even with proper Origin - sources/oauth: fix error whilst fetching user profile when source uses fixed URLs - sources/oauth: handle error in AzureAD when ID Can't be extracted - stages/user_login: add default backend - web: fix title not being loaded from config - web: only report http errors for 500 and above - web: send response info when response is thrown - web/admin: add description for fields in proxy provider form - web/admin: adjust phrasing of cards on overview page - web/admin: fix display for user supseruser status - web/admin: fix error when me() returns 403 - web/admin: fix error when updating identification stage - web/admin: fix invalid group member count - web/admin: fix link to providers on overview page - web/admin: fix mismatched required tags - web/admin: improve phrasing for Policy bindings - web/admin: only allow policies to be bound to sources as users/groups cannot be checked - web/admin: only pre-select items when creating a new object - web/flows: fix Sentry not being loaded correctly See https://goauthentik.io/docs/releases/2021.4#fixed-in-202144
