Redesign LBCS jobs

[lgannoaa]

The following design from the LBCS jobs need to be fixed:
(1) It used nwges directory structure to share data within the same cycle. This solution is not comply with NCO standards. This requirement can be referenced in #459
(2) The LBCS for EnKF (30 members) and the LBCS for ensemble forecast (5 members) output in same directory. Mixing and overwrite output in same location does not comply with NCO standards. Overwriting same LBCs files in the same location at the same time from different jobs may produce unpredictable results and cause result changing errors.
