[Enhancement] Do checkpoint on follower node to relieve memory pressure on leader

[gengjun-git]

Why I'm doing:

What I'm doing:

The current Leader has a Checkpoint daemon thread that continuously checks for new journal dbs. If a new journal db is detected, the following steps are performed:

1. Create a new GlobalStateMgr and load the local image into the new GlobalStateMgr.
2. Replay the journal in the new GlobalStateMgr.
3. Call saveImage to write the metadata in the GlobalStateMgr to disk. At this time, a new image will be generated.
4. Push the newly generated image to other FE nodes.
5. Delete the journal that has been replayed in step 2 from the bdb.

The main differences of the optimized process are as follows:

1. The Leader node is changed from the previous Checkpoint daemon to the CheckpointController daemon, which is responsible for controlling the entire checkpoint process. The check of the new journal db and steps 4 and 5 in the current process need to be completed in the CheckpointController daemon.
2. A new CheckpointWorker daemon is added to the Follower node, which is responsible for executing the checkpoint tasks sent by the leader, that is, 1, 2, and 3 in the current process.
