In a future major version, we will be introducing a soft limit on the number of shards in a cluster based on the number of nodes in the cluster. This limit will be configurable, and checked on operations which create or open shards and issue a warning if the operation would take the cluster over the limit. There is an option to enable strict enforcement of the limit, which turns the warnings into errors. In a future release, the option will be removed and strict enforcement will be the default (and only) behavior.

Backport of #34021, this is just here to get a CI run.
In a future major version, we will be introducing a soft limit on the
number of shards in a cluster based on the number of nodes in the
cluster. This limit will be configurable, and checked on operations
which create or open shards and issue a warning if the operation would
take the cluster over the limit.
There is an option to enable strict enforcement of the limit, which
turns the warnings into errors. In a future release, the option will be
removed and strict enforcement will be the default (and only) behavior.
