Feature request: retry mechanism for model errors

[tsaarni]

I am receiving frequent errors from Gemini models

error="workflow execution failed: failed to call model: Error 503, Message: This model is currently experiencing high demand. Spikes in demand are usually temporary. Please try again later., Status: UNAVAILABLE, Details: []"

I understand that the recommended solution is a retry mechanism (link)

To handle these errors, we strongly recommend implementing backoff and retry (our SDKs support this through retry config).

However, the adk-go or go-genai packages do not appear to have built-in support or hooks for this. It would be great to have a configurable request retry mechanism to handle these cases.
