  - FanoutConfigResourceTest: assert configuration updates being visible
    
    When updating a remote configuration using the FanoutConfigResource,
    the updated values should be also visible in-memory and not simply
    stored on the underlying filesystem.
    
    Fix an issue where the updates to the remotes performed using
    $GERRIT_SITE/etc/replication/remote.config fan-out config scheme
    was persisted on disk but left a stale in-memory copy.
