* added ThingsBoardExecutors and ThingsBoardForkJoinWorkerThreadFactory to define the name for the pool thread * thread poll named for the AbstractListeningExecutor * thread poll named for the RestClient. ThingsBoard util dependency added * most of thread polls named CE * thread poll name added for telemetry-web-socket-ping * executors: added custom names for executors (Queue, RuleEngine). Add topic name to the Thread name (useful for JMX and thread dump) * fixed licence header for a new classespull/4520/head
