If master ends up on a newer version than other cluster members, we
cannot apply the new index setting for shard limits. We skip doing so
for now.

Relates #71392

Will integrate into original 7.x backport in #71760

Will follow-up with a conversion when all nodes in cluster are upgraded to new version (now available in #71781, depending on this PR).

Introduce separate shard limit for frozen shards (#71392) (#71760)
12314f6 
Frozen indices (partial searchable snapshots) require less heap per
shard and the limit can therefore be raised for those. We pick 3000
frozen shards per frozen data node, since we think 2000 is reasonable
to use in production.
