As a result of #45689 snapshot finalization started to take significantly longer than before. This may be a little unfortunate since it increases the likelihood of failing to finalize after having written out all the segment blobs. This change parallelizes all the metadata writes that can safely run in parallel in the finalization step to speed the finalization step up again. Also, this will generally speed up the snapshot process overall in case of large number of indices. This is also a nice to have for #46250 since we add yet another step (deleting of old index- blobs in the shards to the finalization.
