Related to #10741, this adds a new key to app config named
`end_user_authentication`, which can be configured using the same keys
as the existing SSO feature.
Per the spec, if the feature is configured, it's implicitly enabled, at
least until we get to #10999.
Note that this only enables the SSO config, a second part of the ticket
with endpoints for the EULA will be tackled separately.
#8411
We decided to only update roles for existing accounts if enabled by a
new setting (disabled by default) `sso_settings.enable_jit_role_sync`.
