Azure-docs: Confirm reliability level for raising events

[nickward13]

Due to the noted "best efforts" doubts for blob/function triggers (see https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob#trigger---polling), it raises a question about the reliability of event sourcing from Azure blob storage. I understand that the new event sourcing model using Event Grid is more reliable, however it would be great to have this confirmed in the documentation - ie a statement confirming that this eventing model is reliable.

thank you for the feedback! I have added the following statement to the docs to clarify...

"Blob storage events are reliably sent to the Event grid service which provides reliable delivery services to your applications through rich retry policies and dead-letter delivery."

@cbrooksmsft your statement didn't really answer the issue. What is "reliable"? Is it guaranteed "at least once delivery"? Hard to build an enterprise environment with SLAs etc. without some clear descriptive language.
