Async trigger(s)

[Algirdas-Z]

Is your feature request related to a problem?

As a engineer
I want to be able to specify triggers that cobbler doesn't need to wait
so that I can get no 500 errors from apache/gunicorn

Provide a detailed description of the proposed feature

Now, if there is a trigger in cblr/svc/op/trig/mode/post/system/ or any other place for that matter
Which takes long time to complete, we will get 500 error from apache (since proxy request will timeout)

It would be good to have separate endpoint for async triggers or have some sort of argument that I can pass, so cobbler wouldn't wait for it to complete

Alternatives you've considered
