Add JMeter sampler for Azure EventHubs

[stijnmoreels]

While most examples showcase HTTP load tests, other samplers are supported by JMeter as well. One that is especially useful to verify with load tests is Azure EventHubs.

Interesting, thank you to bring this up. Is that xml showcasing a real scenario as you use it? Is important for us to properly defined what are the most common used properties, which should be mandatory and which optional, as to provide the best API and simplify as much as we can the most common scenario.

[stijnmoreels]

It's copied from the referenced repo. Not currently using it, but more wondering if Azure EventHubs should be included as we are currently thinking about writing load tests for it with Abstracta.

[rabelenda]

I think it would be a nice contribution if anyone can implement it in the DSL so we can include it. For Abstracta it would take some time since not much people has requested such feature and seems to be quite domain specfiic. But if more people ask for this we can reconsider. One thing we have in the roadmap is to include some means to use any JMeter element in DSL test plans, as you can do with element() in java DSL.
