[Feature request]: Add AttemptNumber property to HedgingPredicateArguments used in ShouldHandle Func

[renatogbp]

Is your feature request related to a specific problem? Or an existing feature?

I am trying to dynamically control the number of MaxHedgedAttempts options. For example, by default the MaxHedgedAttempts would be respected, however certain flows could require a lower MaxHedgedAttempts value.

Describe the solution you'd like

Having the attemptNumber property inside Func<HedgingPredicateArguments<TResult>, ValueTask<bool>> ShouldHandle predicate would help us to make the decision to skip remaining hedge attempts based on the AttemptNumber.

As a workaround I am setting the Context from OnHedging predicate with the current attempt number. Then we can retrieve the context from ShouldHandle predicate.

It seems a fairly reasonable request to me. The same information is available for the retry strategy.

@martincostello if you agree please assign this ticket to me.

As long as we can do it in a non-breaking way, sure.

Implemented by #2603 - I'll try and do a release containing the change sometime in the next week or so.
