CLI --cluster-ca-delete reports error on 204 status

What happens?

When trying to delete a cluster CA, the following is output:

ERROR: Received unexpected status 204

The delete still goes through fine, as expected from a 204 status

What did I expect?

I expected a success message to be output

Steps to reproduce

1. ++Set up a cluster (defaults are fine)
2. Upload any cluster CA using CLI
3. Delete that CA using CLI e.g.

   /opt/couchbase/bin/couchbase-cli ssl-manage -c localhost:8091 -u Administrator -p password --cluster-ca-delete 1
