Parent: https://github.com/opensearch-project/OpenSearch-Dashboards/issues/895

There is duplication in validation logic that happens to render custom assets so future implementation requires this duplication.

Describe the solution you'd like

Reduction in this logic, but this is a spike task to figure out where this should exist.

Potential options:

• Extending the rendering service with this logic
• Service that components can hook into that assists with the logic
• Branding plugins

Requirements

• Update with findings and design here: https://github.com/opensearch-project/OpenSearch-Dashboards/issues/2044
