Is your feature request related to a problem? Please describe.
Currently it is not possible to configure permissions in GrafanaDatasource.

Describe the solution you'd like
I would like to be able to configure permissions for datasources just like i can do it for GrafanaFolder.

Describe alternatives you've considered

• configure permissions manually
• configure permissions via API-Request

Thanks for creating this issue! If you're up to implementing this, we'd appreciate a PR, but we'll have to spend some time getting CI etc. set up with enterprise licenses as well
