This change creates a /v3/users/{user_id}/access_rules endpoint to allow
users to view and delete their own access rules. Access rules are not
automatically deleted when an application credential is deleted, so they
can be re-used for other application credentials or explicitly deleted
by the user. Access rules are automatically deleted when the user is
deleted, the same way that application credentials are. Access rules
that are in use by an application credential may not be deleted.
