DynamoRaaS update for removal of DynamoController

### Issue

I removed DynamoController/dynSettings, but did not update this external library.  This was an oversight - now fixed.  

### Fix 

The actual code changes can be found here:

https://github.com/pboyer/DynamoRaaS

In short, I make sure to obtain the DynamoModel from the nodes at creation time, and use that to do logging and Dispatcher hooks.  

### Tests

I actually used the nodes and they worked solidly.  I'm looking for guidance about integration tests for this stuff.  This stuff is tough to test because actually using the nodes requires cloud credits and an oxygen login.  If it makes sense, I think these nodes should be part of a manual test procedure before Dynamo release.
