Add lock timeout in DistSQL

[terrymanu]

Add lock timeout in DistSQL LOCK CLUSTER WITH lockStrategy and UNLOCK CLUSTER.

The new attribute LOCK TIMEOUT should be optional. The SQL should be:

LOCK CLUSTER WITH lockStrategy (TIMEOUT int)? and UNLOCK CLUSTER (TIMEOUT int)?.

The todolist should be:

1. Update G4 file
2. Update LockClusterExecutor and UnlockClusterExecutor with Add todo on cluster lock #34133's TODO
3. Update document
4. Add test cases

@terrymanu Hi,I'm sorry. I've encountered some issues while working on this task.
I'm not sure whether the timeout parameter should be added to the LOCK CLUSTER operation TypedSPILoader.getService(ClusterLockStrategy.class, sqlStatement.getLockStrategy().getName()).lock();
or if the timeout in lockContext.tryLock(lockDefinition, 3000L) should be used as the parameter. Could you please clarify?
