dlrm or dlrm-v2 is the official model name?

In the mlperf.conf we have both dlrm and dlrm-v2 and this is confusing to the submitters as to which one to use. Even though dlrm-v2 is the expected one, we have submissions where dlrm is used. Currently, both dlrm and dlrm-v2 are having non-conflicting values, but it is good to clarify this.
