- 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

Code cleanup and incorporate comments from peer review
This closes#323
Fixed nifi-utils pom.xml comment about additional dependencies. (+5 squashed commits)
Squashed commits:
[965b766] NIFI-1753 Removed temporary work-around of duplicate certificate conversion util method and added nifi-security-utils as dependency of nifi-utils.
[cd35f9b] NIFI-1753 Replaced legacy X.509 certificate declarations with new declarations in SSLSocketChannel and EndpointConnectionPool.
Temporary work-around of duplicate certificate conversion util method because nifi-utils cannot depend on nifi-security-utils.
[6420897] NIFI-1753 Replaced legacy X.509 certificate declarations with new declarations in PostHTTP.
[b9868ef] NIFI-1753 Added convenience method for extracting DN from peer certificate chain in SSL socket (canonical implementation to reduce code duplication and references to legacy certificate implementations).
Refactored logic retrieving legacy X.509 certificates with reference to convenience method in NodeProtocolSenderImpl.
Replaced logic retrieving legacy X.509 certificates with reference to convenience method in SocketProtocolListener.
Cleaned up exception handling in SocketProtocolListener.
Replaced legacy X.509 certificate declarations with new declarations in HandleHttpRequest (needs manual test).
[e2d1c35] NIFI-1753 Added convenience methods for converting legacy X.509 certificates and abstract certificates to correct X.509 format.
Added unit tests for certificate manipulation.
Replaced logic retrieving legacy X.509 certificates with new logic in NodeProtocolSenderImpl.
