Fix validation on ExecuteRequest and QueryRequest so that ConsistencyLevel.LocalOne is usable

- It currently checks that the consistency for a query is not >= ConsistencyLevel.Serial (0x0008) when validating the Consistency level for a query which would mean it would reject ConsistencyLevel.LocalOne (which is 0x0010), even though that is a valid value

Fixed LocalOne from 16 to 10
