fall back to old flow if new flow fails

[AlexVulaj]

Hotfix for incident itn-2023-00143

Steps taken to test:

1. On a cluster that was known to be affected by this incident, run ocm backplane cloud console and ocm backplane cloud credentials
2. See that the isolated flow was attempted, failed, and fell back to the old flow as evidenced by a message printed to the console.
3. Take a new cluster that should in fact be using the new flow, run ocm backplane cloud console and ocm backplane cloud credentials
4. See that the isolated flow was attempted and succeeded without falling back to the old flow.
