NIFI-3609: ConnectWebSocket auto session recovery
Before this fix, ConnectWebSocket has to be restarted manually if its
target WebSocket server restarted, or session expiration if there's no
communication more than certain period of time (looks 3 min). This PR adds
automatic session maintenance logic so that ConnectWebSocket keeps its session
alive as long as it's running.
- Removed unused disconnect method from WebSocketService interface.
- Added session maintenance background thread at JettyWebSocketClient
which reconnects sessions those are still referred by ConnectWebSocket
processor but no longer active.
- Added Session Maintenance Interval property to JettyWebSocketClient.
- Allowed specifying existing session id so that it can be recovered
transparently.
- Moved test classes to appropriate package.
- Added test cases that verify the same session id can be used after
WebSocket server restarts.
