Azure Event Hub binding stops working if storage act returns 503

[MattCosturos]

Expected Behavior

Azure Event Hub binding will continue working after receiving a 503 error from the storage act used for checkpointing.

Actual Behavior

The event hub binding dies after receiving a 503 error from table storage. The component does not appear to retry the calls to the storage act, and just gives up. Logs become filled with Error from event processor: the Processor has been stopped. Create a new instance to start processing again

We are using a standard storage act and not a premium act. I could switch to a premium act for better throughput, but I would still have concerns that the component could still fail to process messages if it experiences any sort of transient error.

Can we somehow configure a retry policy to restart this component instead of filling the logs with an error?

Steps to Reproduce the Problem

Unable to reproduce on demand. Leave the component running long enough and this can happen.
