In the current implementation, every time the CeresDB node changes, it will cause large-scale scheduling in the cluster. However, in the actual situation, we hope to control the affected range of the cluster when deploy and debug. Therefore, we need to add a deploy mode switch to control cluster scheduling.
Detailed Changes
Add DeployMode switch in RebalancedShardScheduler, shard topology will be locked when deploy mode is true.
Add some API to control DeployMode.
Test Plan
Pass all unit tests and test DeployMode take effect locally.
