Add a registration function for table allocation in master-slave mode.

[wardlican]

Why are the changes needed?

The HighAvailabilityContainer adds a node registration function. In master-slave mode, each AMS node, after startup, needs to elect a master through ZooKeeper and register its own node information in ZooKeeper. Registration is done using ephemeral nodes. If a node fails, its registration information needs to be automatically deleted. The system also provides the master node with the ability to view the list of currently active nodes.

Close #3919 .

Brief change log

Core functionalities implemented:

1. Node registration:

• In master-slave mode, AMS nodes register their information with ZooKeeper (ZK) upon startup.
• Ephemeral sequential nodes (EPHEMERAL_SEQUENTIAL) are used, automatically cleaned up when a node exits abnormally.

2. Node deregistration:

• Nodes actively deregister from their ZK registration information when shutting down.

3. Live node query:

• The master node can query a list of all currently live nodes. In non-master or non-master-slave modes, an empty list is returned.
