> Currently, task is added to the queue whenever we receive an IActiveContext event. In fault tolerant case, as evaluators can be failed, and we might submit a new evaluator and context, and we need to wait until receiving all the active contexts then start to submit tasks. 
> The TaskSubmitor is responsible for:
> * Creating a new Communication group
> * Preparing task configuration
> * Add tasks to TaskManager
> * Submit Tasks
> The current code need to be refactored to support it.
