Support for all dynamic shovel properties

[mhewedy]

The com.rabbitmq.http.client.domain.ShovelDetails lacks most of the dynamic shovel properties. Like the ability to auto-delete the shovel using src-delete-after.

As I workaround, I created a subclass for ShovelDetails object and added the properties I needed.

It should be nice if we can configure the complete list of the properties out-of-the-box.

@mhewedy this is open source software. Since you've already solved the problem, consider contributing instead of asking others to do it?

I like the idea ... I will prepare the PR soon..
@michaelklishin I think I will need to add the properties into the ShovelDetails itself.. ?
