Handle different JobParametersModels in one ConcurrentQueue

[alessandroros]

This is not an issue but the only way to discuss with the author of this great solution. First of all thanks for this repo and your contrib. I wanted to ask you if you have ever thought about having "etherogeneous" JobParametersModels in the JobModel class?

What I would like to accomplish is to have a ConcurrentQueue handling these jobs and not to creating many ConcurrentQueues each of them of different type.
