Replace Certbot with Lego for Let's Encrypt container

Replaces Certbot with Lego for certificate retrieval and renewal.
Lego includes support for DNS ACME Challenges.

Adds ssh-client to LetsEncrypt and ssh-server to HAProxy to allow both
the transfer of Let's Encrypt certificates to the HAProxy container and
to enable live updating of HAProxy certifices using the HAProxy API
exposed on the local HAProxy socket.

Implements: blueprint letsencrypt-https
