KUDU-2230: java: sync client exception stack traces should make sense

Previously the exceptions thrown by the synchronous client always had
a stack trace somewhere deep inside our async callback chain. So, when
the user eventually caught this exception, it would be very hard to even
know what part of their code failed, since their own code would not even
show up in the call chain.

This patch simply replaces the exception's stack trace with the stack at
the "join" point where the exception is transformed back to a
KuduException. An exception which stores the original stack trace is
attached as a "suppressed" exception.
