Graham Hayes 0a983719b6 Add __str__() methods to DesignateObjects
This allows for easy logging of objects

* __str__() implemented in base DesignateObject
* Builds Message based on 'STRING_KEYS' list in objects
* Record has overridden implementation to limit the size of data attr

Partially-Implements: blueprint bp/standardize-logging
