Allow unregistered options to be ignored in DBOptions from files (#9045) 

Summary:
Adds changes to DBOptions (comparable to ColumnFamilyOptions) to allow some option values to be ignored on rehydration from the Options file.  This is necessary for some customizable classes that were not registered with the ObjectRegistry but are saved/restored from the Options file.

All tests pass.  Will run check_format_compatible.sh shortly.
