Consider using "ApproximateReceiveCount" attribute to compute number of immediate processing failures for ErrorContext

Describe the feature.

Is your feature related to a problem? Please describe.

The number of immediate processing failures is tracked per physical endpoint deployed. This means the actual number of immediate processing failures can exceed the limit before delayed processing kicks in. This can also lead to increased cost.

Describe the requested feature

The ApproximateReceiveCount attribute could be used as the number immediate processing failures passed to the ErrorContext.

I think it starts at 1, so subtract 0 (with a floor of 0) to compute the number of immediate processing failures.

This could be an opt-in setting for now, or perhaps the default behavior in a major upgrade.
