Important notices
Before you add a new report, we ask you kindly to acknowledge the following:

• [v] I have read the contributing guide lines at https://github.com/opnsense/plugins/blob/master/CONTRIBUTING.md
• [v] I have searched the existing issues, open and closed, and I'm convinced that mine is new.
• [v] When the request is meant for an existing plugin, I've added its name to the title.

Is your feature request related to a problem? Please describe.
Receiving a wildcard certificate only worked once. When the time came for a renewal I would always get propagation check errors. Research brought me to these parameters which fixed the problem.

Describe the solution you'd like
Adding those two parameters to my Caddyfile fixed a problem I was having retrieving wildcard certificates for my domain.

Describe alternatives you've considered
There are none

Additional context
The Caddy team added the parameters because many people had issues with retrieving wildcard certificates.

Caddy forum post: caddytls: Add propagation_delay, support propagation_timeout -1

Documentation around the tls module and propagation parameters are here: tls docu

NOTE:

The current Caddyfile generated by the plugin creates levels: tls > dns
This will need to be changed to: tls > issuer acme > dns

The "issuer acme" level will need to be added for the propagation properties to be available. Structure is as follows:

*.example.com { tls { issuer acme { dns provider { api_key xxxxxxx ... } propagation_delay 30s propagation_timeout -1 } } ... }

Hey, do you want to try adding that? If not, I can do it, but it might take a while since Im busier now.

Sadly enough I'm not capable to do this myself, otherwise I would have gladly helped.

To me it's not that urgent. As long as I don't change my config now, the parameters will keep working.

I found the flag and set it, then saved and applied. The properties are added correctly, the Caddyfile is valid, so I assume everything is ok. I cannot validate completely at the moment but I will be able to check the wildcard certificate retrieval soon.

Thanks for adding a patch for this issue so quickly, that was quite remarkable!
