Nova compute: add in log exception to help debug failures
When the system is under load, there can be boot failures. One exception seen in the log file is: ''NoneType' object has no attribute 'status_code'' There is no log trace which helps pinpoint this client call. Note that this is only one example. We now add in a LOG.exception to have the stack trace. Related-Bug: #1850682 Change-Id: I2ab56005db363f81eecf07c3db62c267ba7f8ca9 (cherry picked from commit9062fd3923
) (cherry picked from commit35b5dc0d97
