    Just the properties in here.  Couple thoughts as you bring this up.
    We probably want to have a ticket to make sure turning off Kerberos works correctly in
the future.  The properties in the file (except nimbus.seeds) are essentially set properties.
 We need our own client_jaas, and the storm.thrift.transport has to be there for some reason
and that's pretty much constant on a secure cluster.  That should also be made a property
that flows down from Storm.
    nimbus.seeds is wrong and I need to carry that over from the actual Storm property. And
I even made sure it was in params_linux and forgot to use it.
