[actions] create a generic webhook endpoint for testing actions

[pmuellr]

While trying to diagnose a problem with a customer using an action, I happened upon https://pipedream.com , which is a service which allows you to create "webhook" endpoints on their server, and then be able to see the incoming requests to the webhook.

A capability like this could be useful in Kibana itself. To help diagnose action issues, customers could point to an endpoint we provide in Kibana specifically to test http actions tied to specific URLs, by using this "test" interface instead.

I haven't looked too deeply into pipedream. I'm not sure that providing absolutely correct HTTP responses for any service would be required, for diagnostic purposes, it's seems like usually we just want to see what the request ends up looking like on the server. So it could always return a 404 response, or such.

But we'd want to capture the requests so that you could then see what requests had been made, after the fact. And then have some UI for it, etc, etc.

One could complicate things with webhooks triggering specific actions or Elastic could implement a more generic JSON-RPC Connector that stores session based tokens for reuse

Unfortunately I don't have any news when Fortinet is going to implement a standard API
