@LagunaElectric We already have this feature open so I don't see you opened a new one

@Nikhil-Nandagopal The other two requests are for specific platforms, and I created this after the Hashicorp request because I think it would be better to support external providers in general. I think this issue is more robust because it would pave the way to allow any external provider we choose to support such as Doppler, Cyberark, Azure Key Vault, etc. In my mind I imagined this issue as an Epic with those two existing feature requests as the first two integrations.

I can imagine a checkbox or toggle during datasource configuration to decide wether to enter credentials manually or use an external provider. If they choose to use a provider they would be able to select one from a dropdown and configure it with their datasource. Maybe they can connect to their secrets managers at the workspace level, and then reference those connections in their datasource configurations.

We have a general request here #7454 so there isn't a need for a new one. I think we're covered and we'll figure out the right solution
