A dummy {@link ReplicationEndpoint} that replicates nothing.
<p/>
Mainly used by ITBLL to check whether all the entries in WAL files are fine, since for normal
case, we will only read the WAL files when there are region servers crash and we need to split
the log, but for replication we will read all the entries and pass them to the
{@link ReplicationEndpoint}, so setting up a replication peer can help finding out whether there
are broken entries in WAL files.
