Editing OpenSearch Cluster Installation (section)

=== Security Plugin Initialization ===
Once all security configuration files are finished, they must be loaded into the OpenSearch cluster.  This can only be done once enough of the cluster is up to provide a master node and at least one data node, as the security configuration is loaded into an index in the cluster.  See the instructions below for specific sequencing.  This command will initialize the security plugin:
 plugins/opensearch-security/tools/securityadmin.sh \
     -cacert config/<CA cert> -cert config/admin.crt -key config/admin-pkcs8.key \
     -cd plugins/opensearch-security/securityconfig/ -host master-1.opensearch.localnet -icl -nhnv
... but again -- wait to do this until the right time below.
