Parent status based on it's child issues and vice versa.

Scenario A:

When a Task, Story or an Epic child issues such as sub-tasks, move from TO DO to IN PROGRESS, the parent issue should also move to that status.

Scenario B:

When all the child issues are on DONE status, the parent issue should be consider as DONE too. The same should happen when the parent is consider a completed issue (all its sub-tasks should move to Done status).
