Liang Chen d1da173017 Enable unicode error message
Keystone exceptions could only take byte string message as the
message arguments to construct exception instances because of
the way its super class StandardError implements __unicode__.
This patch can also make sure it would not unintentionally remove
line breaks and indentation in a explicitly given message argument.

Fixs bug #1168879
