scheduler: Log error if scheduled task cannot be submitted

Logs error if scheduled task cannot be submitted (which means that
the task is dropped), so administrators can easily find out that
Quartz thread pool has been depleted and no other scheduled task
will be executed until some already running thread is returned
to the pool.
