Fix indentation of option parameters
Catch and retry object load on component load errors

In case an object can't be loaded, retry up to 5 times. Load errors can
happen in case a chef server is too busy with other requests. All knife
and chef-client requests do the retry already, so that change is more or
less replicating that behavior here.
