[CARBONDATA-2230][BACKPORT-1.3]Add a path into table path to store lock
files and delete useless segment lock files before loading
After PR1984[https://github.com/apache/carbondata/pull/1984] 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.
