  1. DAOS-16469 dtx: properly handle DTX partial commit 

    When a DTX leader globally commit the DTX, it is possible that some
DTX participant(s) cannot commit such DTX entry because of kinds of
issues, such as network or space trouble. Under such case, the DTX
leader needs to keep the active DTX entry persistently for further
commit/resync. But it does not means related modification attched
to such DTX entry on the leader target cannot be committed, instead,
we can commit related modification with only keeping the DTX header.
That is enough for the DTX leader to do further DTX commit/resync
to handle related former failed DTX participant(s).

The benefit is that VOS aggregation on the leader target will not
be affected by remote DTX commit failure.
