Description of problem:
it's hard to test whether a webhook was correctly configured (in terms of endpoint, authentication, etc) without performing the actual action it is subscribed to

Version-Release number of selected component (if applicable):
6.13.0 (but also all previous containing foreman_webhooks)

How reproducible:
100%

Steps to Reproduce:
1. create a new webhook
2. try to fire it, without performing the action it's subscribed to

Actual results:
not possible

Expected results:
I'd expect at least a way that the right type of request (POST) is sent to the right endpoint using the right authentication method.

It might not contain the correct payload and thus the other side might still reject it, but at least I can see that the overall HTTP call worked.
