Setup nginx config with https using
ssl config provided by let's encrypt and my standard
location for storing certs.
EXTRA_SETTINGS_FILE can be - for stdin
--p PORT Proxy to PORT
--h|--help Print help and exit
--- Subsequent arguments are never treated as options
+-c CERT_DIR In priority: this arg, $ACME_TINY_WRAPPER_CERT_DIR,
+ $HOME/webservercerts, if the other options aren't set.
+-f [ADDR:]PORT Enable proxy to [ADDR:]PORT. ADDR default is 127.0.0.1
+-p PORT Port to listen on, default 443
+-r DIR DocumentRoot
+-h|--help Print help and exit
-Note: options and non-options can be in any order.
TODO: add https redir site.
