WorkQueue: Add possibility to enable metrics

Because the handling of metrics for queues created
from plugins is a bit problematic, a new method createQueue
with extra parameter: withMetrics has been introduced.

At the moment the only queue that has metric enabled
is default WorkQueue. Other queues will be added
in a follow up patch.

For each queue created using this method the
following metrics are available:

* active_threads - Number of threads that are actively executing tasks
* max_pool_size - Maximum allowed number of threads in the pool
* pool_size - Current number of threads in the pool
* scheduled_tasks - Number of scheduled tasks in the queue
* total_completed_tasks_count - Total number of tasks that have completed execution
* total_scheduled_tasks_count - Total number of tasks that have been scheduled
