As a user of POMBA, I would like additional support for data dictionary integration to enable building of more powerful validation rules.

The data dictionary API is defined in

  https://wiki.onap.org/display/DW/Integration+with+Data+Dictionary

I expect validation service to support the following use cases 

1. Please get me the list of valid values for this attribute
2. Here is a subset of attributes in a larger reference table/object, please return full rows that match subset. Note, subset could be one attribute.
3. Here is a fully qualified row in a reference table/object, please tell me if it's valid

Success Criteria

• Above features are supported
  • Data Dictionary is successfully reachable
  • Data Dictionary successfully used in validation rules executing all of the above use cases - happy and unhappy paths
• Code tested and checked in
• Relevant wiki pages are updated
• Data is retrieved and available for use locally
• Failure to retrieve dictionary results in relevant log entries + flow continues based upon available contexts.
