Distinguish BadVersion a real exception or false positive for retry

[tison]

Hi ZooKeepers,

When investigate this issue[1] I notice a possibility that if I write such
a program:

while (true) {
try {
  zk.setData(path, data, version); // (1)
  break;
} catch(KeeperException.ConnectionLossException e) {
   // retry
}
}

... then in (1) there can be a case that it throws
KeeperException.BadVersionException but actually the action is successful
on the server side previously (but failed to send a response due to
connection loss).

Is this investigation right? If so, it is possibly to distinguish whether
we succeed to apply the op on the server side?

Best,
tison.
