[mod] upgrade to Caddy v2

* Use docker image caddy/caddy:2-alpine * Caddyfile: remove "limits 10KB" * Caddyfile: URL /filtron/rules removes (filtron API still availabled on http://localhost:4041/rules ) * .env: Remove SEARX_PROTOCOL, SEARX_TLS, FILTRON_USER and FILTRON_PASSWORD variables. * docker-compose.yml: filtron and morty listen on 127.0.0.1
