Event fired to SessionLockListeners around acquisition and release of a Vaadin session lock.

The same lock instance protects a session whether it is acquired by the framework while handling a request or via VaadinSession.lock() (for example from UI.access(Command)). A listener receives SessionLockListener.lockRequested(com.vaadin.flow.server.SessionLockEvent), SessionLockListener.lockAcquired(com.vaadin.flow.server.SessionLockEvent) and SessionLockListener.lockReleased(com.vaadin.flow.server.SessionLockEvent) on the same thread for a given outermost lock-hold, so timing state can be kept in a thread local.
