Get records from harvest DB

[rshewitt]

User Story

In order to get records from the harvest database to run our compare, datagov wants to implement retrieving harvest records from our harvest DB and converting them into an id: hash format similar to what is implemented now for ckan

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• [ ] GIVEN harvest.py
  AND a job id WHEN a call to the associated functions are called
  THEN records will be read and converted into id:hash format \

Background

Security Considerations (required)

[Any security concerns that might be implicated in the change. "None" is OK, just be explicit here!]

Sketch

• get records by source using existing route
• convert records into id:hash format
• ensure compare works properly
