storage: different subpaths can point to same root directory

currently different subpaths can only point to same root directory only
when one or both of the storage config does not enable dedupe

different subpath should be able to point to same root directory and in
that case their storage config should be same i.e GC,Dedupe, GC delay
and GC interval
