Importing a feed that uses a controller service to another environment fails to update Kylo metadata with new controller service reference
1. create a Sqoop or Data Ingest feed using a Controller service to pull from a source
2. save and export the feed.
3. import this feed to a new environment
4. if you edit the feed the controller service will have the id from the first environment.
Kylo is not updating the feedMetadata property for the new controller service id upon import to the new environment.
KYLO-3204 should fix this
