Event Grid subscription on blob storage with event hub

- [ ] bug report
- [x ] request for new sample
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Hi,

Is there a sample anywhere that shows how to create an event grid subscription on a blob storage account? I would like to then make the end point topic an event hub.

There are samples for event hubs but its complicated to wire up the event subscription on a blob storage account and i just keep getting 400 bad request errors.

Thanks
Doug

Start by reviewing the existing Event Hubs samples in this repository and the Azure service APIs for blob storage, Event Grid subscriptions, and Event Hubs. Add a Go sample that wires a blob storage account to an Event Grid subscription whose endpoint is an Event Hub, and verify that it avoids the reported 400 Bad Request errors.
