Add upload_status into CrashReportInfo proto

Consider that the crash collection in local device doesn't promise the
reports are uploaded in a specific duration, we have to add a new field
into proto to let DM server know the upload status. The corresponding
detailed crash reports cannot be found in crash servers if their status
are not 'uploaded'.
