Worker Metrics.

this is a worker model so it has following duties to do: run containers, accept task from manager, provide stats and keep track of tasks state for running containers and keeping track of the state we can store it on map which can then implemented to etcd since we would implement the task in a queue(FIFO) we would do this with normal golang-collections library at last keeping the count of the task in the queue as task-count.
