LU-2886 mdd: create local files using local_storage lib

Switch MDD to use local_storage library to create local objects with
generated or pre-defined FIDs. That unifies the way how local objects
are created on both OST/MDT and avoid layering violation with calling
MDD from OSD like md_local_object library does.

two other fixes are included:
- remove DECLARE_LLOG_WRITE/REWRITE and mdd_declare_llog_record()
  which was a temporary solution to declare llog changes and was
  fixed with llog-over-osd implementation
- add .lustre seq range into FLD in fld_insert_special_entries() as
  all other special ranges.
