Review request for bookkeeper.
Summary
-------
bookkeeper client treats NoSuchLedgerException as valid response when reading
last confirmed. If NoSuchLedgerException is caused due to an empty directory in
following cases, it is an incorrect response.
1) A disk is replaced or ledger index is removed by a sloppy admin.
2) A disk is not mounted when a bookie machine is restarted.
We need a mechanism to prevent such incorrect responses.
Ivan suggested to generate a instance key for each bookie and write it into the
ledger directories. If a directory doesn't have the key, and other directories
do, then it shouldn't start. This would also resolve the issue that someone
starting a new bookie with the same IP as a bookie which has previously died.
This addresses bug BOOKKEEPER-163.
