- 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
- Populating component entities in the REST API to decouple key fields from the configuration DTOs.
- Added initial support for components in UI when access isn't allowed. Formal styling to come later.
