updateDependentTaskDueDate

This suspend function updates the due date of the dependents of the current Task, based on the date of a related Immunization. The function loops through all the tasks that are part-of the current task, loads the dependent tasks and their related immunization resources from the DefaultRepository then updates the start date of the dependent task if it's scheduled to start before the immunization date plus the required number of days.

This function can be extended in future to support other ResourceType s.
