Minor Description
After PR1984 merged, it doesn't delete the lock files when unlock, there are many useless lock files in table path, especially segment lock files, they grow after every batch loading.
Solution :
1. add a child path into table path, called Locks, all lock files will be stored in this path;
2. Before loading, get all useless segment lock files and delete them, because just segment lock files will grow, other lock files dosen't grow.
