cbtransfer error: AttributeError: 'module' object has no attribute 'loads'

Summary: Error message when running cbtransfer. Couchbase Server 5.0 running on Ubuntu.

Repro:

1. Create bucket called metrics-metadata
2. Put at least one document in the bucket (see example below, the exact document may not matter)
3. Use cbtransfer to export to csv with the command: ./cbtransfer -b metrics-metadata --key=metrics\.content_partner:.* -u Administrator -p password http://localhost:8091 /mnt/storage/content_partner.csv

Expected:

CSV file should be created.

Actual:

Error message:

Notes:

I tried this with 5.5 on Windows and it seemed to work correctly (no error message). This may be a Linux-only issue or it maybe a 5.0 issue (link to original forum post in comments).
