Add Caddy import support #1
Description
We have an SSL certificate generated by https://caddyserver.com/ located at /var/lib/caddy/.local/share/caddy/certificates/acme-v02.api.letsencrypt.org-directory/unifios.synergi.tech/
We need to add support for this to be imported into unifi os. Modify the existing .sh file to add Caddy support. We should not need to generate new SSL certificates; we only need to import the new ones, as Caddy handles generation.
