Sometimes the real content of a MySQL connection failure is several wrapped exceptions deep. For example, socket-level errors like Connection Refused/Reset and SSL version errors report a fairly bland "Communications link failure", without giving any real clues about the problem. This commit walks the nested exceptions on a DB connection failure and logs them all out.
