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

We currently don’t have a resource detector for DigitalOcean Cloud in the resourcedetectionprocessor. This makes it impossible to automatically enrich telemetry with DigitalOcean metadata when running on their cloud.

Describe the solution you'd like

Add a new DigitalOcean detector that uses the official DigitalOcean metadata API client to detect resource information (server ID, hostname, region, etc) and populate the corresponding OpenTelemetry resource attributes.

Describe alternatives you've considered

I am willing to sponsor such a detector. See #35091 and #42632 for an example of adding a new resource detector.

Are you interested in implementing and being a codeowner for it?

[paulojmdias]

@dashpole sure! The PR is already open #42804.

I'm also proposing to be a codeowner for it, and I kept you and @Aneurysm9 there 🙏
