Yanqin Jin f307479ba6 Enable checkpoint of read-only db (#4681 An error occurred ) ... Summary: 1. DBImplReadOnly::GetLiveFiles should not return NotSupported. Instead, it should call DBImpl::GetLiveFiles(flush_memtable=false). 2. In DBImp::Recover, we should also recover the OPTIONS file name and/or number so that an immediate subsequent GetLiveFiles will get the correct OPTIONS name.
