Wrap service ensure in manage_service boolean

As it happens already for the other services, this will prevent
puppet from enforcing the backup service into
either running or stopped state when manage_service is false.

Also adds validate_bool for 'enabled' and 'manage_service' to
the api, scheduler, volume and backup services.
