fix(clouddriver): Return a call stack for better error handling

[wattdave]

We are seeing large numbers of "NullPointerException" from this particular exception in our CloudDriver logs, and we would like to isolate where underneath the problem lies. The code as written prints only the exception name in the logs, with no stack trace.

Pretty sure https://github.com/spinnaker/clouddriver/pull/5585 fixes that error, which is why I updated your branch to pick it up.
