Adding provider attributes to ActiveJob

Hello,

Looking into ActiveJob a bit, it seems

similar to carrying along the provider’s Job ID ( https://github.com/rails/rails/issues/18821 ), providers should be able to include additional meta data about the job; things that would not be appropriate as arguments because they’re related to the job itself and are handled / generated by the provider.

My current use case is using Shoryuken, I would like to access some of the meta data about the job (i.e. when was it first queued).

It seems like a fairly straightforward addition, I am willing to put together a PR, but I’m interested to see if there was a conscious decision to not include it.

Thanks,

Bob
