[Improve][Manager] Combine schedule state transition with group operations

[aloyszhang]

Description

Currently, the group and schedule are managed individually. But the schedule states are mainly controlled by the group operations, like :

• schedule info should be saved when group saved
• schedule info should be removed when the group is deleted
• schedule info should be updated when the group is updated
• schedule info should be registered to the schedule engine when the group approved

This issue aims to combine the schedule stats with the group operations.
