NIFI-950: Still seeing some slow response times when instantiating a large template in cluster mode so making some minor tweaks based on the results of CPU profiling
NIFI-5112: Refactored FlowSerializer so that it creates the desired intermediate data model that can be serialized, separate from serializing. This allows us to hold the FlowController's Read Lock only while creating the data model, not while actually serializing the data. Configured Jersey Client in ThreadPoolRequestReplicator not to look for features using the Service Loader for every request. Updated Template object to hold a DOM Node that represents the template contents instead of having to serialize the DTO, then parse the serialized form as a DOM object each time that it needs to be serialized.
NIFI-5112: Change ThreadPoolRequestReplicator to use OkHttp client instead of Jersey Client
NIFI-5111: Ensure that if a node is no longer cluster coordinator, that it clears any stale heartbeats.
NIFI-5110: Notify StandardProcessScheduler when a component is removed so that it will clean up any resource related to component lifecycle.
NIFI-950: Avoid gathering the Status objects for entire flow when we don't need them; removed unnecessary code
NIFI-950: Bug fixes
NIFI-950: Bug fix; added validation status to ProcessorDTO, ControllerServiceDTO, ReportingTaskDTO; updated DebugFlow to allow for pause time to be set in the customValidate method for testing functionality

NIFI-950: Addressing review feedback
NIFI-950: Fixed validation logic in mock framework

Updated PropertyDescriptorDTO to contain AllowableValueEntity to retain readability permission
Added entity class for AllowableValueDTO
Moved AllowableValueDTO to its own top-level class

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.
Code cleanup and incorporate comments from peer review
This closes#323
