Installs and configures Caddy for use as a local ACME CA server allowing certificates to be issued in testing.\
By default, the Caddyfile defaults to 1 month for the leaf certificates and 1 year for the intermediate certificate.\
To use the same certificates for all VM's that use this role, create directory `./files/certs` in the root of the repo, and using for example scp or sshfs move the certificates from one your VM's to the directory.\
The location of the certs is usually `/var/lib/caddy/.local/share/caddy/pki/authorities/local`. Simple copy-paste everything from there to your host machine and into the role directory.\
This is for mostly convenience, as multiple VM's might use this role so you only need to import the `root.crt` to your browser once.
In your playbook, define the role and config paths. Most likely the defaults are fine, so you can just simply add the role. Remember to add this before any certbot role. The ACME server is hosted at port 8443. You can also change the `templates/Caddyfile.j2` to fit your own needs.\
