Commit 04c41c0654b166c9f42844cc9907ea791f4563bc in nifi's branch
refs/heads/master from [~markap14]

NIFI-1678:
- Started refactoring heartbeating mechanism, using a new package:
org.apache.nifi.cluster.coordination
- Added configuration options for ZooKeeper username & password for heartbeat
management. Also addressed issue where nodes that were previously disconnected
were asked to disconnect upon restart
- Ensure that ACL is set properly when creating heartbeat node. Removed unused
ControllerStartupFailureMessage.java
- Changed ZooKeeper ACL's so that container nodes that would not be sensitive
are wide open and removed the usage of username & password when communicating
with ZooKeeper. This was done specifically because username/password
combination is considered a 'testing' feature that should not be used in
production and is not supported by Apache Curator
- Refactored CuratorHeartbeatMonitor into an abstract heartbeat monitor that is
responsible for processing heartbeats and CuratorHeartbeatMonitor that is
responsible for retrieving heartbeat information
- Refactored so that heartbeats are sent to Cluster Coordinator directly
instead of to ZooKeeper. ZooKeeper is used to know which node is the cluster
coordinator but heartbeats to the Cluster Coordinator provide additional
information about the nodes.

NIFI-1727:
- Refactored logic for merging HTTP Requests that are federated across cluster
NIFI-1745:
- Refactoring how HTTP Requests are replicated to nodes
- Bug fixes and continuing to work on replication refactoring. Still need to
handle cluster locking and revisions
- Begin work on RevisionManager
- Resolved some issues that resulted from rebase
- Fixed URIs to align with new URI's that will be used in 1.0.0
- This closes #413

> Currently, all of the logic to federate requests exists within the
> WebClusterManager class. This needs to be refactored into better encapsulated
> code so that the logic is more easily moved to the nodes.
