The change https://git.opendaylight.org/gerrit/c/controller/+/59294
proposed a default configuration where the parameter maximum-message-slice-size replaced shard-snapshot-chunk-size which is deprecated.
But this parameter is commented out so not really declared.
In this situation, controller/cluster/datastore/DatastoreContext.java will set up a
default datastore context parameter and it will retrieve a shard-snapshot-chunk-size default value from raft (controller/cluster/raft/DefaultConfigParamsImpl.java)
And this will generate the following misleading warning:
"The shard-snapshot-chunk-size configuration parameter is deprecated - use maximum-message-slice-size instead"
as observed in release CSIT
