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.

Changed ControllerServiceNode by adding enable(..), disable(..) and isActive() operations. See javadocs for more details in both ControllerServiceNode and StandardControllerServiceNode
Refactored service enable/disable logic in StandardProcessScheduler and StandardControllerServiceNode . Below are some of the notes:
- No need for resetting class loader since its going to derive from the class loader of the service. In other words any classes that aren’t loaded and will be loaded within the scope of the already loaded service will be loaded by the class lower of that service
- No need to control 'scheduleState.isScheduled()’ since the logic has changed to use CAS operation on state update and the service state change is now atomic.
- Removed Thread.sleep(..) and while(true) loop in favor of rescheduling re-tries achieving better thread utilization since the thread that would normally block in Thread.sleep(..) is now reused.
- Added tests and validated that the race condition no longer happening
Added additional logic that allows the initiation of the service disabling while it is in ENABLING state. See javadoc of StandardProcessScheduler.enable/disable for more details.

Current implementation of DBCPConnectionPool was attempting to test if connection could be obtained via dataSource.getConnection().
Such call is naturally a blocking call and the duration of the block is dependent on driver implementation. Some drivers (e.g., Phoenix - https://phoenix.apache.org/installation.html)
attempts numerous retries before failing creating a deadlock when attempt was made to disable DBCPConnectionPool which was still being enabled.
This fix removes the connection test from DBCPConnectionPool.onConfigured() operation returning successfully upon creation of DataSource.

Before this change, the host given out to clients to connect to a Remote
Process Group Input Port is the host where the NiFi instance runs.
However, sometimes the binding host is different from the host that
clients connect to. For example, when a NiFi instance runs inside a
Docker container, a client on a separate machine must connect to the
Docker host which forwards the connection to the container.
Add a configuration property to specify the host name to give out to
clients to connect to a Remote Process Group Input Port. If the property
is not configured, then give out the name of host running the NiFi
instance.
