As Developer
I want to be able to leverage the new ML capabilities in OpenSearch (https://opensearch.org/docs/latest/ml-commons-plugin/)
so that I can use new features like Semantic search, leveraging external models etc.
There are various cluster settings that needs to be exposed to the end-users to enable these features.

The most urgent is "onlyrunonmlnode" which is set to "true" in Aiven Clusters. This needs to be set to "false" to allow ML workloads to be executed on any node (until we have the capability to assign dedicated ML-nodes in the cluster)

There are more configs that needs to be exposed but "onlyrunonmlnode" is a direct blocker for any ML use-case.
