Is your feature request related to a problem? Please describe.

Adding an optional setting that controls the permissions of data source to create, update and delete. data_source.editMode: "read_only|admin_only|none" "read_only": The data source is readonly for all users including OSD admin. "admin_only": The data source can only be edited by OSD admin((https://github.com/opensearch-project/OpenSearch-Dashboards/issues/6389) ). "none": The data source can be edited by all users. Default to "none".

Describe the solution you'd like

Before editing a data source, data source permission client wrapper will verify the data source edit mode.
