  - Fix error updating request_processing_data

    Fix error when updating existing record in request_processing_data
    table.
    Use correct field name in the toString method in RequestProcessingData
    bean class.
    RequestDbClient.updateRequestProcessingData should include entity id in
    the URI on the PUT request.
    Add new Config class ExposeEntityIdResourceConfiguration to make
    Spring data Rest return id in the response for RequestProcessingData.
    Make spring-boot-starter-data-rest not optional dependency in
    mso-requests-db-repositories
    Added unit test for RequestDbClient.updateRequestProcessingData()
    method.
