[Suggestion] Allow loading wildcard certificate from file system

What would you like to be added or improved?

There seems to be several issues requesting to support wildcard domain certificate via dns-01 challenge. (Mainly #563 )
Currently, the only way to allow wildcard certificate to be used is via uploading a file or manually pasting the content of the certificate in the web interface, which can't seem to be automated. (Unless you go by controlling a headless browser to do so...)

The linked issue seems to suggest by supporting various DNS providers for TXT record updates, but can you simply allow reading the certificate from the container's file system as that seems to be a lot simpler than supporting various DNS providers, but those are already well supported by CLI tools like certbot which can be automated and a hook can make SafeLine be reloaded upon a new certificate is issued to load the updated certificate from the mounted file system within the container.

Why is it needed?

There doesn't seem to be a way to automate to load a renewed wildcard domain certificate.

We've added it to the roadmap! Thanks!

SafeLine WAF now supports updating SSL certificates through file upload.
