Hangfire Passing Global Parameters on Job Creation

https://github.com/HangfireIO/Hangfire/pull/570
At GrowthZone, we needed a way to pass parameters when creating recurring jobs. However, we didn't want to include these parameters in every job creation as they were unrelated to the job task or business logic.

Initially, we used the JobFilterAttribute to obtain parameters from the IoC container. We added these parameters to the create context and retrieved them during job execution. Unfortunately, this approach didn't work for recurring jobs because the IoC couldn't fetch the parameter values from its previous context or instance, which was destroyed when queuing the job during the AddOrUpdate call.

To address this, we sought a solution to attach parameters to recurring jobs during the queuing or serialization stage. This way, we could access them again from the parameter list in the create-context instance when the job was loaded or deserialized.

We explored exposing access to the parameters property in the create-context instance to achieve this. This allowed us to add parameters to it, ensuring they could be serialized and saved to disk when adding a recurring job.
