Task scheduler

• Tasks can be scheduled with dependencies with other tasks.
• Allows manual actions on tasks using cli.
• Multiple tasks can be wrapped under a bundle task.
• Task can have dependencies, by setting a prerequisite (start condition) - task will only be executed if the condition satisfied.
• Tasks can be inserted/updated/deleted via specific syntax task action definition.
• Task can be scheduled with batch run or window run or manual run.
