Build Cluster object for ZooKeeper the same way as for Etcd
...
Previous implementation was always setting Cluster.initialize to True.
Also it was throwing ZooKeeperError when there were no members in a
cluster.
Plus BUGFIX of a bug introduced with
https://github.com/zalando/patroni/pull/34 in a `load_members` method.
- data = self.get_node(self.member_path)
+ data = self.get_node(self.members_path + member)
It was always fetching the same node for all cluster members.
Fortunately Etcd doesn't have such problem because we are fetching the
whole cluster directory with one recursive API call.

Move PostgreSQL data directory if init had failed.
...
Prevent treating the incompletely-initialized PostgreSQL cluster
as a valid on restart by forcefully moving the data directory.
I don't want to remove it altogether, since a DBA might decide
to analyze the failed PG cluster in order to resolve the init
issue.

If initializer node suddenly dies before the initialization is complete,
other nodes should try to take over.

Make sure initialize flag is reset on failure.

Cleanup the initialize flag if the initializing node fails
to bootstrap its PostgreSQL database.
Rename dcs.race to initialize, since we only call it for the
initialize flag. Factored out PostgreSQL bootstrapping code
