[BUG] Added datasources not visible in security analytics

[kritikashahi]

What is the bug?
Added multiple datasources in opensearch for remote clusters. The added datasources shows up in dropdown in devtools but not in security analytics. In security analytics, datasource defaults to local cluster, although a newly added datasources is added as default.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Add datasources in opensearch
2. Go to security analytics and click on Local Cluster (written on top right corner)
3. Check the available datasources present in dropdown
4. It shows only 1 option i.e Local Cluster.

What is the expected behavior?
All the added data sources should be present in dropdown for selection in datasources in security analytics

What is your host/environment?

• OS: linux
• Version: 2.16.0
• Plugins: security analytics

Do you have any screenshots?
All datasources available for selection in dev tools
