feat(storage): encrypted secret values (#2588)
This adds an AES-GCM 256bit encryption layer for storage for sensitive items. This is only TOTP secrets for the time being but this may be expanded later. This will require a configuration change as per https://www.authelia.com/docs/configuration/migration.html#4330.

Closes #682
