Description

Presently OM has four combinations, which leads to complexity as objectStore#rename can't be differentiated with fs#rename.

1. ofsOptimized=true && enableFSPaths=true
2. ofsOptimized=true && enableFSPaths=false
3. ofsOptimized=false && enableFSPaths=true
4. ofsOptimized=false && enableFSPaths=false

This jira proposal is to simplify the ofs optimization cases. OM can support ofs optimization only if both are TRUE(ofsOptimized=true && enableFSPaths=true) and will write table key entries in NEW_FORMAT(prefix separated format using objectID). All the other cases, it will write table key entries in OLD_FORMAT(existing format).
