Siying Dong 4774a9409b Allow option string to get comparator from object registry (#5106) 
Summary:
Even customized ldb may not be able to read data from some databases if
comparator is not standard. We modify option helper to get comparator from
object registry so that we can use customized ldb to read non-standard
comparator.
