    Affects Versions: 2.1.0
            Reporter: Eren Avsarogullari
            Priority: Minor


Support some Schedulable variables immutability and access

Some Schedulable variables need refactoring for immutability and access modifiers as follows:
- from vars to vals(if there is no requirement): This is important to support immutability as much as possible. 
Sample => Pool: weight, minShare, priority, name and taskSetSchedulingAlgorithm.
- access modifiers: Specially, vars access needs to be restricted from other parts of codebase to prevent potential side effects. Sample: 
Sample => TaskSetManager: tasksSuccessful, totalResultSize, calculatedTasks etc...
