What happened?

Installer panics when attempting to create an IBM Cloud IPI cluster. The cause appears to be due to failed client VSIProfile initialization via the ibmcloud client and this caused the installer to panic
```

What did you expect to happen?
Installer would provision IPI resources in IBM Cloud.


How to reproduce it (as minimally and precisely as possible)?
Using an IBM Cloud installer build, and install-config.yaml

$ openshift-installer create cluster ...

Anything else we need to know?

IBM Cloud will be working to provide a fix to check the `err` prior to attempting to return profiles.
