[LU-4460] Using multiple NIDs for the same failnode or mgsnode is STILL broken for Lustre 2.4

It seems to me this bug is still there for 2 reasons:
This is a follow-up of ~~LU-3445~~.
This ticket was supposed to fix this problem. However, it seems to me this bug is still there for 2 reasons:

-the patch only take care of mkfs/tunefs and so there is still an upgrade issue if mountdata contains something like failover.node=10.3.0.228@o2ib,192.168.50.128@tcp
The way to workaround this looks to be a writeconf, which has side effect. Is there some UPGRADE notes somewhere relative to this?

-the patch seems to modify this kind of string

--failnode=10.3.0.228@o2ib,192.168.50.128@tcp

into

--failnode=10.3.0.228@o2ib --failnode=10.3.0.228@o2ib

Which is not the same. The first example refers to 1 failnode, with 2 NIDS to reach it. The second one refers to 2 different failnodes with 1 NID each
