code: public int getHashedPartitionForParameter(int partitionValueType, Object partitionValue) {
          final VoltType partitionParamType = VoltType.get((byte) partitionValueType);
          return getHashedPartitionForParameter(partitionParamType, partitionValue);
      }
docs: Given the type of the targeting partition parameter and an object,
  coerce the object to the correct type and hash it.
  NOTE NOTE NOTE NOTE! THIS SHOULD BE THE ONLY WAY THAT YOU FIGURE OUT
  THE PARTITIONING FOR A PARAMETER! THIS IS SHARED BY SERVER AND CLIENT
  CLIENT USES direct instance method as it initializes its own per connection
